Anyone has an idea to prevent/eliminate a 502 gateway error? Please lend some knowledge.
I’ve done all I can think of and researched extensive yet some users are experiencing it

Thanks

Your server is probably killing certain processes because they are too large. Have you tried running load tests to see which processes take the longest to execute?https://tools.pingdom.com

Increasing buffer size from your server config file might fix it.

If you have root level access, you can try having a look at your nginx logs in /var/nginx/error.log.

Usually, this error comes from you having a proxy server doing something else somewhere, you can try to check if it’s resolving correctly.

Check if your server’s FQDN is resolving correctly too. But the log files first.
