Hi,
My website has been running since I deployed it yesterday.
I rebooted the server this morning, and now the website won’t load.
Im using nginx and gunicorn - i have tested both and the tests were successful.
What reasons are there that the website now wont load, after nothing was changed during the reboot
502 Bad Gateway means nginx is unable to communicate to gunicorn.
Make sure that gunicorn is running on the expected port. You can verify it using :
netstat -tulpn
If you find it running and the website still shows 502, try restarting nginx and gunicorn.
Let me know if you have any further questions.
I can’t see gunicorn in the table (posted below), i’m assuming that’s the issue? It’s strange as when I run sudo systemctl status gunicorn.socket, it says gunicorn is active

What errors you find with “tail -F /var/log/nginx/error.log”
Probably there is a problem with the sock file.
