    It looks like it was Fail2ban adding my server IP that caused this issue for me. I tried the steps in this article but httpd would not restart. I had to run Plesk Repair to fix it.

    Hope this helps someone else!

    Had 502 Bad Gateway and this nginx error in the logs: 

    671#0: *1 connect() failed (111: Connection refused) while connecting to upstream

    Serving IPV4 and V6 and fail2ban running. Restarting fail2ban and setting the own IPs as trusted IP solved the issue.
