Check for problems with server connectivity
Most websites are hosted by third parties or use many servers. Your website may display a Bad Gateway 502 Error page to users if your server is offline due to maintenance or for maybe any other reason.
Waiting for your server to complete the maintenance or resolving the issue that is causing the error are your only options for troubleshooting this issue.
Operating a mock test to check if the messages are reaching your server IP could be a quick approach to determine if you should be contacting your hosting service.
Look for any DNS modifications
The DNS server for your website will change if you recently switched host servers or transferred them to a new IP address. This can result in your website sending a 502 Error page to users.
It may take a couple of hours for the DNS changes to fully take effect, at which point your site will not be operational.
Check your log for errors
Your server’s status and health can be found in detail in the server logs. Screen through them to find any troubling information and act on it.
Correct misconfigured firewall settings
Your firewall acts as the gatekeeper for your website, guarding it against malicious users or DDoS (Distributed Denial of Service) assaults.
A Bad Gateway 502 Error may occur when your firewall incorrectly interprets requests from CDN (Content Delivery Networks) as an attempt to attack your server and rejects them. To identify and resolve the problem, check the settings of the firewall.
Look for flaws in the coding of your website
Your server may not be able to accurately respond to requests from a CDN if there is a bug in the coding of your website. To detect bugs, go through your code or paste it into a development environment.
It will carry out a detailed debugging procedure that will recreate circumstances in which your 502 Bad Gateway Error happened and let you know exactly when things went wrong.
