Rudder

After upgrading Rudder-root-server from 6.0.0 to 6.0.1 I cannot login to webinterface. Ubuntu 18.04.3 LTS. Everyting working before the apt upgrade.

Getting below error in apache-logs (/var/log/rudder/apache2/error.log:

Getting below errors in stderrrout.log (/var/log/rudder/webapp/2020_01_03.stderrout.log):

Server is listening on the ports:

Not sure if this is relevant, but syslog shows:

Tried to restart services + full server reboot. Same error.
