Error 502, bad gateway.

Postby Totte » Mon Sep 11, 2017 10:56 am

Hi, recently I've been getting error 502 from CloudFlare. My server has been running just fine for over 3 years and this problem appeared out of nowhere. It's been almost 2 weeks now and I can't figure it out. It even went to the point where I installed the server entirely, still getting the same problem.

My nginx error.log is empty.
Apache looks more or less like this

Code: Select all

Mem/CPU/HDD looks all fine both in htop and running HP's system health check thing.

So I found another nginx log inside the Vesta folder.

My /var/log/nginx/domains/ folder is empty tho, or is there another location for domain logs?

Someone may close the thread. Solved it by changing to Virtualmin.
