ExecStart=/usr/bin/docker run -p 6789:6789 --name=nzbget --restart=always -e PUID=1000 -e PGID=1000 -e /etc/localtime:/etc/localtime:gb -v /opt/nzbget:/config -v /mnt:/Downloads lsioarmhf/nzbget
ExecStop=/usr/bin/docker stop -t 2 nzbget
ExecStopPost=/usr/bin/docker rm -f nzbget

[Install]
WantedBy=default.target

and the output of sudo systemctl status nzbget
$ sudo systemctl status nzbget -l

Hi,

I got the same problem you have, I solved by replacing the “docker run” command by a “docker start”.

Once your container is created with a name, you may start/stop it from the .service file. You should simply replace:

ExecStart=/usr/bin/docker run -p 6789:6789 --name=nzbget --restart=always -e PUID=1000 -e PGID=1000 -e /etc/localtime:/etc/localtime:gb -v /opt/nzbget:/config -v /mnt:/Downloads lsioarmhf/nzbget

by:

ExecStart=/usr/bin/docker start -a nzbget

All the port forwarding are started as expected, as it uses the same container you created (using the docker run command).

Hope it helps.
