I have a site “ forum.6figureswithchris.com ” it was working fine behind a proxy port 8080 and I have apache on port 80 but suddenly it gives “502 bad gateway” ##this is the all-in-one, standalone Discourse Docker container template ## ## After making changes to this file, you MUST rebuild ## /var/di…

Solved. It was firewall blocking several processes.

Ohh! Allright! I only understand now. I’m sorry but I won’t be of much help as my general troubleshooting suggestions don’t work with cpanel. I’d suggest you move your discourse to a separate server instead.

Ohk, thanks anyways. btw the server is centos vps and it has like 5 cpanel for 5 websites.

You’re running probably a very puzzled variant as in my experience there is a lot of struggle getting discourse to work on centOS let alone cpanel which is neither recommended nor easy to get going.

i know right. but it was working for 5 days completely ok but suddenly this error showed up. Is there any other way to check if memory is free? I read many threads saying its a memory error for sure

This is not a memory issue if you can get it working on an alternative port :wink:

As I’ve suggested earlier, drop the idea of running it alongside cpanel Just spin up a $5 droplet on DO and install afresh. It will be the most certainly works kind of solution I can give you right now.

If it was working before, I suspect it’s a Discourse problem. Have you rebuilt lately? Are you using any non-official plugins?

How can it be that it works fine on other ports but not on port 80 though? I suspect it’s cpanel and it’s firewall doing weird things.

I had rebuilt once and it caused problems. But I did a complete clean install of everything related docker and discourse exactly as I did earlier, the problem still persists.
