I recently encountered the error "502 Bad Gateway" on my website, which uses a reverse proxy setup. This error intermittently appears, especially during high traffic periods. I suspect it might be related to server overlaod or perhaps misconfiguration issues.
Can anyone suggest what specific settings should be checked or optimized in a typical reverse proxy configuration to minimize the occurrence of 502 errors? Additionally, are there recommended monitoring tools or logs that could provide more insight into what triggers these errors at certain times?
Any advice on troubleshooting steps would also be greatly appreciated!
