Shutdown

[hdswiss]

Shutdown works when I enter this command in the console:
sshpass -p "xxxxxxxxxxxxxxxxxxxxxxx" ssh -o "StrictHostKeyChecking=no" -p xxxxx [email protected] "sudo poweroff"
But unfortunately, it doesn't work via UpSnap.

Have you tried this command inside the docker container?

docker exec -it UpSnap sh
sshpass -p "xxxxxxxxxxxxxxxxxxxxxxx" ssh -o "StrictHostKeyChecking=no" -p xxxxx [email protected] "sudo poweroff"

Also, you have specified password (-p) twice.

The first -p is for the password, and the second -p is for the port.
