502 - Bad Gateway
You get a 502 Bad Gateway Error when the server fails to respond accurately and returns the request with invalid information. However, there are other possibilities; knowing them is crucial to troubleshooting this error effectively. This is typically due to a low-resource server (shared hosting or micro VM) expected to host a high volume of requests.
- Your server is busy with other tasks or hit by traffic spikes
- Origin servers are unresponsive or inaccessible
- Errors in the database
- Problem with the reverse proxy server
- Corrupt PHP scripts in WordPress files
- DNS issues
To troubleshoot and resolve the issue, you may need to look into each of these possible causes and take the appropriate action. This may involve working with your web hosting provider, disabling plugins or themes, checking your server logs, or consulting a WordPress developer or security expert.
If hosting is a related issue, we recommend upgrading your hosting or contacting your hosting provider to allot more resources.
