This is the server's way of alerting the user that something unusual has disrupted the Internet database connection. The bad or inadequate responses received at the end of a server can happen when the server is overloaded or if the network connection between two servers is not present.
These are some of the main issues that result in 502 bad gateway errors. While you are addressing these issues, you should also look at the configured firewall to check any coding error.

Restart your Device
Our mobile phones and tablets run on high-end hardware and operating systems, so they always work in the background. In some cases, 502 bad gateway errors can be caused by these background processes, and the best way to stop them is by restarting your mobile or tablet.
Try Reloading the Website
This is probably the most common fix for 502 bad gateway errors, and it is mainly for users, not developers. Reloading pages and websites reduce the load on the server, and after a couple of seconds, the site will come back.
If this does not work, you should try using a different browser to resolve the issue. If the problem persists, you need to check whether the site is down permanently or just for you.
Reset Internet Configuration
Your internet modem can also be a problem when facing such errors, so it is better to reset internet configurations and check if the page loads or not. You can either switch off the router or disconnect your computer from that particular network and connect it again.
Clear your browser's cookies
When your browser is outdated or filled with corrupt files, you will face such errors, and they will keep coming back if you don't remove cached files and cookies. You can clear them by selecting the advanced option from the settings and press "clear data."
Check your Plugins
Plugins and extensions associated with your website can be one of the reasons causing this problem. If you see some unusual activity taking place when some extensions are enabled, you need to turn them off one by one and find the culprit responsible for these constant errors.
Try Changing your DNS Servers
DNS problems are not likely to cause 502 errors, but it is still a possibility. If you set up DNS servers by yourself, you can make some adjustments without needing third-party software. On the other hand, if your ISP installs your DNS servers, you will need OpenDNS or Google DNS to solve the problem.
Scan for Viruses

Using robust anti-virus software, you can effortlessly detect and remove malware. However, this still doesn't solve the entire problem because you still can get infected if you don't follow certain precautions while using the web.
It is recommended only to use verified websites and scan every email you receive. They may contain malicious links that redirect users to malware-containing sites. One final tip to avoid malware and prevent such error messages is not installing anything that is not a developer's website.
Use Airplane Mode
One can enable and disable the airplane mode to observe changes in the web page. This process solves the internal problem with network components. If any program is stuck, it gets activated again to operate smoothly. The airplane mode is visible on any device under network settings.
Update the Network Driver
Network drivers have unique functionality that enables the operating system to communicate with the Wi-Fi module. However, these drivers tend to function incorrectly when it is not updated, so it can be the reason why you are repeatedly experiencing such 502 errors.
To fix outdated network drivers, you should first go to the device manager and select storage controllers. Once you find Intel drivers, you should right-click and select Update Driver Software.
Check Firewall Settings

An important thing to consider here is that these websites are blocked for a reason, and that can be due to malware also, so make sure to research the website before you remove it from the list.
