I have installed indico according to the setup in the docs but i cant seem to run the site. When i try running it in the browser i get a 502 Bad Gateway error. I have tried possible solutions that were recommended here but none seemed to work. When I check /opt/indico/log/nginx/error.log i get this upstream prematurely closed connection while reading response header from upstream. But the logger sends a complete trace of the programming error to my email and I guess that’s where my problem is. The machine am using has apache2 installed on it yet am using the indico nginx installation guide. I simulated the installation on a virtual machine before and it was working fine. I need help.
The trace:
