Can't connect to Urbackup (img via docker)

Hello,

is successfully upgraded my urbackup installation and installed Urbackup via Cockpit inteface:

Normaly i should reach the urbackup server via the IP adress of my openemediavault server and the the ports :55415 or 55414 or 55413 but i cant connect ?

My second question - how can i restore my urbackup installation(files are backuped)

best regards

I can now connect to Urbackup, strangly you have to import the container via the terminal:

docker run -d --name urbackup-server-1 -v /media/backups:/backups -v /media/database:/var/urbackup -p 55413-55415:55413-55415 -p 35623:35623/udp uroni/urbackup-server

But does anyone know how to restore my old urbackup server ? the path is also invalide. Has docker R/W rights? Where is this set?

Im completely new to docker....
