502 Bad Gateway
I have JATOS installed on a VM rented from my university. The IT specialists there helped me install JATOS with a nginx proxy.
Today I started getting a "502 Bad Gateway" nginx error. I tried restarting jatos with systemctl (which has worked before) but now the issue is not resolved.
I checked "systemctl status jatos.service", maybe its output helps:
I'm not sure if the "unknown lvalue" error was occuring before.
Any pointers as to where to problem may be are super appreciated!

Our IT guys checked our the "application.log" and saw that the Jatos JAVA process is crashing. Seems to be happening since the latest update.
I've little idea how to navigate the log, so I'm just going to attach it here in case it helps:

Hi Yavor,
I can see in the log that you are using an external MySQL as a database and JATOS cannot connect to it anymore: "org.hibernate.exception.JDBCConnectionException: Unable to acquire JDBC Connection"
Can you tell your admin to check if the MySQL database is still running and accessible?
Best,
Kristian
Thank you for the reply! Somehow the admin fixed it, I'm not sure exactly how.
Apparently he saw in the logfile that a new version of a configuration file is available, so he merged the new and existing versions, and it's back up and running.

Nice!
