Hello 
I try to run urbackup on unraid in docker and it works fine until I stop and restart the container then I get the error in the logs: WARNING: Error: Unknown action [login] and the web-gui wont load at all.
There are two docker repos, Binhex and masterwishx - urbackup official, tried both, same happens.
If I clear all the config files and reinstall the container it works again untill next time its restarted.
