Refreshing the page can reload the webpage and may fix the issue. To refresh the page, click on the refresh button on your browser or press F5 on your keyboard.

This is not really anything drama related, but just a general problem on DA. Has any one else dealt with this annoying glitch where when you refresh your page, you get an error message? It happens to me all the time! I have to wait a few minutes to reload it before it goes back to normal again. I hate it and wanna know if anyone else deals with this inconvenience -_-

I can actually answer this somewhat. It is true, I experience this often. It will say something like...

"Guru meditation, llama on fire" - One part of the site loads faster than another that should've loaded first. A good analogy to think of is the teleportation system from Star Trek and how you could end up on the other end with your body arranged differently.

"Something's gone wrong" - Usually just a hiccup in the system, often the page loads too abruptly or something. Another loading-based error.

"Service temporarily unavailable" - Something in the HQ malfunctioned or is being worked on.

"Looks like our server's having a meltdown" - This is caused by stress in the system. We all have meltdowns sometimes. Sometimes these meltdowns are caused by actual meltdowns, for example a fight broke out in one of the monthly selfie threads in the forums and people started spamming each others' pics, some of which were extracted from me.

"502 bad gateway" - If you have any numerical error, check your IP, your VPN, and your device. Numerical errors are most common in people who were never told the mobile experience has been abandoned by DA because it requires cooperation with phone tech and sometimes phone tech goes loose cannon. Also, turn off your VPN, it doesn't help you here.

"The server encountered an internal error" - Kind of like the blue screen of DA. These are fixed when someone comes around to it.

How to Fix a 502 Bad Gateway Error on Your WordPress Site?

The 502 Bad Gateway error indicates that an incoming server sent an invalid response to the server.

The 502 Bad Gateway error is defined by the Internet Engineering Task Force (IETF) as follows:

The 502 (Bad Gateway) status code indicates that the server, while acting as a gateway or proxy, received an invalid response from an inbound server it accessed while attempting to fulfill the request.

After much wailing and gnashing of teeth

Got hooked last night trying to make NGINX Proxy Manager behave.

It's the morning after now, after I gave up with it not fully working.

Trying to stitch together the bits I had wrong that I needed to fix for next time.

Excerpt from a rant to a friend:

I got annoyed by trying to learn computer things and think I've cracked it as I get into bed and boooo I'm not getting back out to try it now

I don't like not immediately knowing something

Just feels like having to brute force my way through and finding the answer by accident, not actually understanding

Now, what did I brute force.

Starting: NGINX Proxy Manager up, but no dice.

Cross referenced two videos

https://www.youtube.com/watch?v=CSbgLBcIuwE

https://www.youtube.com/watch?v=rpUEw4yBMnA

Also had to reinstall MariaDB and NGINX Proxy Manager because I hadn't saved the username/password I'd used for NGNIX. Oops.

Second video keyed me into opening port 80 to avoid having to do a DNS lookup.

Success! I was able to get an SSL cert.

And I have my own domain and a mostly static IP, so used that rather than duckdns (I think I can use duckdns as a workaround if I had a dynamic IP? will review sometime, perhaps)

But then I was getting an error 400 whenever I hit the domain.

Did some digging: https://old.reddit.com/r/homeassistant/comments/og1hao/400_bad_request_error_behind_nginx_proxy_manager/

Need to update some config in homeassistant in order to use a reverse proxy.

To do that, had to find out how/where to edit the configuration.yaml.

To do that, I had to get a new add-on for home assistant.

Say hello to VSCode!

Then struggled fro a while working out how to enter the config changes in a way that HA liked.

Eventually got there, including a bit where I absolutely just copy-and-pasted the same thing and it worked the second time when it didn't work the first time. Infuriating.

Left myself some notes to this effect:

that IP that works appears to be the standard IP NGINX uses. I don't know why/where - does this mean I have a VM (NGNIX) hosted on a VM (HA) on my Hypervisor (The Dell box)?

Probably.

SO then!

I was resolving with I typed in the domain. Yay.

But only sometimes.

SSL on - fail.

SSL off - success.

Curious.

Went to bed.

did more research in bed.

Hadn't port forwarded port 443 for https! - https://community.home-assistant.io/t/external-access-no-longer-working-via-duckdns-nginx-proxy-manager/478460/4

Got up the next morning... port forwarded 443...

And now I get a 502 Bad Gateway.

While experimenting, I found that Let's Encrypt only lets you request a cert for a specific set of domains 5 times in a week. And all my recreations to try to experiment with things burned this up. So now I have an SSL Cert valid for two domains, one of which is super long because I messed up!

And then worked out why I was getting a bad gateway:

THIS is referring to the internal address being on http (D'oh) or https, not the external - https://www.thesmarthomebook.com/2021/08/25/nginx-proxy-manager-setup-and-a-fix-for-your-502-gateway-errors/

So I was getting a bad gateway because I was asking for an https connection between the proxy and HA, which it couldn't do.

Change that to HTTPS - success!

Good grief this is hard work.

Next step - Make a Nextcloud VM and see if I can make a new NGINX entry to reverse proxy to that on a different subdomain.

How to troubleshoot the Uverse gateway authentication failure?

Since the internet has become an important part of our day-to-day life, the method which we use to connect to the internet has become important to us too. Depending on various parameters, we use different methods like modems, routers, and dongles to connect to the internet. Even though the technology in these parts is advancing pretty quickly, it is inevitable to have occasional problems. AT&T U-Verse provides an efficient and robust Internet Protocol TV (IPTV) service but if you are a user of U-verse modems, you might be encountering a problem where you keep getting an error of authentication failure. Looking to get rid of the Uverse gateway authentication failure? Here, we are going to cover almost everything about this authentication failure!

The question of “why does my Uverse internet keep dropping?” might have been bugging your so we are gonna help you to solve that problem and help you have an amazing internet browsing experience.

As for everything, the first step of solving a problem is to identify the causes of that error.

What causes the gateway authentication failure ATT?

There are different reasons behind this error like the default gateway is not available, and the 502 bad gateway. One of the main reasons for such a problem occurs when the loading configuration is corrupted due to a sudden power shut down while the modem is building up the launch configuration and the loading time in the initial stage is increasing. This severs the communication between the server and the modem, presenting the error of gateway authentication failure. Any time the router’s configuration gets corrupted suddenly, there is a chance that this error might occur.

Also if the network equipment has faults then it also can cause issues such as ISP authentication failure. If the Ethernet cord is not connected to the correct ONT port, you might also encounter this problem.

These are the common reasons why the error of gateway authentication failure occurs. Now that we know what can cause it, let us see how you can fix it. The steps are really simple so you will not have to worry about having to execute serious mechanical procedures.

How to fix the gateway authentication failure? -Uverse gateway authentication failurePower cycle the router

This is the most basic way of troubleshooting most of the issues of a router. Power cycling is a little bit more elaborate than restarting a device. It drains the power capacitors and fixes many issues related to firmware and corrupted temp files. The steps of power cycling the router are given below.

Remove the power adapter from the modem and wait for it to shut down. Take the modem to a different location or keep other electronic devices away from the modem because the WiFi signals of the modem should not be intercepted by them. Wait for a couple of minutes before connecting the power adapter to the socket again. Then turn on the modem and wait for it to show the full signal. Now you can open the browser and connect to the internet and see if this process has solved the error or not.

Do you want to fix the 502 bad gateway error on your site? This error is quite annoying because it can be caused by a lot of different things. This means troubleshooting the 502 bad gateway error can take some time. In this article, we will show you how to easily fix the 502 bad gateway error in WordPress.What is a 502 Bad Gateway Error?A 502 bad gateway error is triggered when your WordPress hosting server gets an invalid response for the requested page. Bad gateway error is one of the common WordPress errors that you may encounter on your site. It can be caused by a number of reasons and depending on your server the error message may also differ in looks slightly. When you visit a website your browser sends a request to the hosting server. The hosting server then finds the page and sends it back to your browser with the status code. Normally, you wouldn’t see this status code. However, in case of an error the status code is displayed with an error message. Examples of such errors include 404 not found, 503 service unavailable, 403 forbidden error, and more. The most common reason for a 502 bad gateway error is when your request takes too long for the server to respond. This delay can be a temporary glitch caused by high traffic. It could also be a glitch caused by a poorly coded WordPress theme or plugin. Last but not least, it can also happen due to a server misconfiguration.That being said, let’s take a look at how to easily fix the 502 bad gateway error in WordPress. Fixing the 502 Bad Gateway ErrorThis error is usually caused when your server is unable to find the cause of the invalid response. This means that we will try different troubleshooting steps until we find the problem. Ready, let’s get started. Step 1: Reload Your WebsiteSometimes your server may take longer to respond due to increased traffic or low server resources. In that case, the problem may automatically disappear in a few minutes. You should try reloading the web page that you are viewing to see if this was the cause. If this fixed your problem, then you do not need to read any further. However, if you see this error frequently, then you need to continue reading as there may be something else that needs fixing. Step 2: Clear Browser CacheYour browser may be showing you the error page from the cache. Even after the issue is fixed, you would see the 502 error because the browser is loading your website from cache. To fix this, users with Windows/Linux operating systems can press Ctrl + F5 buttons and Mac OS users can press CMD + Shift + R buttons on their keyboards to refresh the page. You can also remove the cache manually from your browser settings.Once you clear your WordPress cache, try loading the website again.You can use a different browser to troubleshoot if the problem is occurring because of browser cache. If you see the error on all browsers, then continue reading.Step 3: Disable the CDN or FirewallIf you are using a CDN service or website firewall on your website, then it is possible that their servers are acting up. To check this, you will need to temporarily disable CDN. Once disabled, it will remove the additional layer that has been created between your browser and the hosting server. Your website will now load entirely from your server and if the issue was caused by the CDN / firewall service, then it will get resolved now. You can then contact your CDN service provider for support. Once the issue is resolved, you can go ahead and enable the CDN again.Step 4: Update WordPress Themes and PluginsIf the error is still there, then the next step is to check your theme or plugins. First, you will need to deactivate all WordPress plugins via FTP. After that, visit your website to see if the error has resolved. If it is, then one of your plugins was causing the issue. You now need to activate all plugins one by one until you can reproduce the error. This will help you locate the plugin responsible for the error. You can find an alternative plugin or contact the plugin author for support. If deactivating plugins didn’t solve your issue, then you would want to check your WordPress theme. You will need to switch WordPress theme via phpMyAdmin. After switching your theme to the default WordPress theme, visit your website to see if it’s working. If you are still seeing the error, then continue reading. Step 5: Check the Hosting ServerIf all above-mentioned troubleshooting steps failed, then it is likely an issue with your hosting server. You need to contact your hosting provider’s support team and let them know the issue. You can also mention all the troubleshooting steps you have taken. All good WordPress hosting companies will be able to quickly fix the issue if it is caused by a server misconfiguration. That’s all.

How to Fix 502 Bad Gateway Error?

Here are some very simple ways of fixing 502 Bad Gateway errors from the client side.

Reload the page

The first thing you should do is reload the page and wait for a minute. If the 502 Bad Gateway error disappears, it means there was a temporary problem with the upstream server or the networking between servers. If the error remains, check if the site is down for everyone. You can use Is it down right now? for this. If the site is up for everyone except you, open the site on another browser or in private mode.

Clear browser cache

Another easy tip is to clear the browser cache. If the error disappears after cleaning cache, it means that there was a temporary problem that has been resolved, but because of cache, you kept seeing the 502 Bad Gateway error template, instead of your website. If the error remains, try the next tip.

Flush DNS cache

The 502 Bad Gateway error can occur because of DNS issues. Operating systems, such as Linux, Windows, and macOS save name resolution information in the form of a DNS cache. In many cases clearing the DNS cache can solve a 502 Bad Gateway error. Here are the commands which you can use for flushing DNS cache on Windows, MacOs, and Linux. Use this command to flush cache on Windows:

ipconfig /flushdns

On macOS, you should open the terminal and type:

sudo killall -HUP mDNSResponder

There’s no message after processing this command, but you can add your own by running the command like this:

sudo killall -HUP mDNSResponder; dns cleared successfully

Things are different in Linux, as different Linux distributions use different DNS services. Some of them are NSCD (Name Service Caching Daemon), dnsmasq, and BIND (Berkeley Internet Name Domain). For an NSCD DNS cache:

sudo /etc/init.d/nscd restart

For a dnsmasq DNS cache:

sudo /etc/init.d/dnsmasq restart

For a BIND DNS cache:

sudo /etc/init.d/named restart

sudo rndc restart

sudo rndc

exec

If the terminal asks for your password, just enter it.

Change DNS servers

You can also try to temporarily change your DNS servers. More information about changing DNS servers can be found in this article: Change your DNS servers settings.

If you’re using Cloudflare

Cloudflare returns a Cloudflare-branded HTTP 502 error when your origin web server responds with a standard HTTP 502 bad gateway: This means that something is wrong with your origin server and you can try to use the above-described tips to fix the issue. If the 502 error is from Cloudflare, the page looks like this: If the error contains the word “Cloudflare,” the problem comes from Cloudflare, otherwise, it is from the origin server. In the first case, you can contact Cloudflare support, and in the second case, you can follow the described tips. If nothing helps, contact your hosting provider. You can read more about Cloudflare 5xx errors in the article Troubleshooting Cloudflare 5XX errors.

We’ve discussed some client-side tips which can help you troubleshoot a 502 Bad Gateway error. Now let’s see what you can do on the server-side.

Restart PHP

The very first step is to restart your PHP. With 10Web, you can do this by going to Hosting Services > Tools and clicking the blue “Restart PHP” button. If your hosting doesn’t provide an interface for restarting PHP, ask them to do it for you.

Check logs

Checking your server error logs can give you very useful information about 502 Bad Gateway errors. With 10Web, you can easily check server logs by going to Hosting Services > Logs. If you have access to your file system, you can check server logs. In the case of the Nginx web server, you can find logs here:

/

var

/log/nginx

In the case of Apache web server, the logs are in this repository:

/

var

/log/apache2

Improper firewall configuration

Improper firewall configuration can lead to 502 Bad Gateway errors. A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. It typically establishes a barrier between a trusted network and an untrusted network. There can be cases that some awkward firewall settings can consider safe and valid content malicious and, consequently, cut off traffic which in turn cause 502 Bad Gateway errors. Check your firewall configuration to reveal any improper configs.

Third-party plugins & themes

Non-optimal codes in WordPress plugins and themes can also cause 502 errors. So, check your plugins and theme. If you have access to your WordPress admin, deactivate all your plugins, and if the error disappears it means that there is at least one guilty plugin. Then activate them one by one to find the guilty ones. If your WordPress admin area can’t be reached because of the error but you have access to your WordPress files, just rename the plugins directory in wp-content. It will deactivate all plugins. And again start activating them one by one.

If the problem isn’t the plugins, that is deactivating all plugins or renaming plugins directory doesn’t change anything, try to temporarily change your theme to WordPress’s default theme. Once you find the bad plugins or theme, connect to the respective support team and describe the issue. And don’t forget to keep your plugins, theme, and WordPress core up-to-date. This will help you avoid many problems, including 502 errors.

Restart PHP-FPM service

You will get a 502 error if the PHP-FPM service is inactive or not running on your server. If you have access to your hosting, you can check this by running one of the following commands. For SysVinit:

sudo service php7.4-fpm status

For SystemD:

sudo systemctl status php7.4-fpm

If the service is active and running, the output of the command should be like this: If the status is not Active: active(running), try restarting PHP-FPM service to resolve the error using one of the following commands. For SysVinit:

sudo service php7.4-fpm restart

For SystemD:

sudo systemctl restart php7.4-fpm

Timeout issues

The 502 error can be caused by a PHP-FPM timeout. If your application is taking too long to respond, your users will experience a timeout error. If the PHP-FPM timeout is less than Nginx timeout, Nginx will return a 502 Bad Gateway error. To avoid this, you can increase PHP-FPM timeout if you have access to your server.

PHP-FPM timeout is set in pool configuration which is

request_terminate_timeout

The default value for this directive is 20 seconds. If you don’t have access to your server, ask your hosting provider to check it. To avoid getting 504 errors after increasing PHP-FPM timeout which can be because of Nginx timeout, the default is 60 seconds, you can increase fastcgi_read_timeout directive in /etc/nginx/nginx.conf file. Don’t forget to reload the Nginx server after changing the directive:

nginx -s reload

PHP execution time errors can also lead to 502 Bad Gateway errors. To avoid this, you can increase the PHP configs, such as max_exexution_time and max_input_time.

If you have your server access, just change these directives in your php.ini file. If not, ask your hosting provider to do it for you.
