Note - NGINX running on ubuntu:19.04 container
Any ideas please?
Thanks,

Sorry for the delay in responding. It looks like it is failing to connect to the database, and I see "port = 0" in the log. Any chance that's the issue (port is usually 3306).

Hey Nigel,
I've managed to solve the issue on my own but I'll note in case it will help anyone else.
My issue was that the NGINX and MySQL were on diffrenet containers, therefore I had to make sure I create appropriate connections in the MySQL server (rather than having the default 'root@localhost').
Once I've created a new user with permissions for the relevant database and allowed connection from any host ('%') the issue was resolved.
Thanks,
Lior
