Getting 502 Error on existing nginx server
Created by: tomtom87
Hi, I am trying to run the gitlab community edition on my debian box which currently has a few vhosts configured in a nginx installation.
The two are working side by side ok, I set the gitlab port to use a different one to the port 80 the existing nginx was working on.
The only problem is now when I submit forms on my existing nginx I get a error 502 unless I restart the service for every request (obviously no fix, but interesting)
Here are the errors from the /var/log/nginx/error.log
