Quick Summary
Error 502, also known as 'Bad Gateway,' indicates that the server you're trying to access is acting as a gateway or proxy and received an invalid response from another (upstream) server. This often means the problem lies with a server that Website relies on to fulfill your request.
Common Causes
- Server Overload: The upstream server might be experiencing a high volume of traffic, causing it to become overloaded and unable to respond properly.
- Network Issues: There could be network connectivity problems between the servers, preventing them from communicating effectively.
- Server Maintenance: The upstream server might be undergoing maintenance or experiencing unexpected downtime.
- Firewall Issues: Firewall configurations between servers could be blocking communication.
- Code or Application Errors: Problems within the Website code or its dependencies can cause the upstream server to return an invalid response.
- DNS Resolution Issues: If the Website is unable to resolve the domain name of the upstream server, it can lead to a 502 error.
