Problem running docker as systemd service, won't start gives a error

[tenwa]

I'm trying to get the docker container to run as a service with systemd, as the example in the documentation, but it keeps throwing a error.

This is what I get from systemctl status

transmission-openvpn.service - transmission-openvpn docker container
     Loaded: loaded (/etc/systemd/system/transmission-openvpn.service; disabled; vendor preset: enabled)
     Active: activating (auto-restart) (Result: exit-code) since Sun 2023-07-09 18:03:03 BST; 4s ago
    Process: 3699 ExecStartPre=/usr/bin/docker kill transmission-openvpn (code=exited, status=217/USER)
    Process: 3700 ExecStartPre=/usr/bin/docker rm transmission-openvpn (code=exited, status=217/USER)
    Process: 3701 ExecStartPre=/usr/bin/docker pull haugene/transmission-openvpn (code=exited, status=217/USER)
        CPU: 15ms

my service config file is as follows

The docker run command is the same as I use from shell script, to run it which works fine, I'm at a it of a loss as what the error message means, done the usual searches, and not found anything enlightening.

Sorted, me being stupid, in the attempt to test it, I had edited the config line, to reduce the number of vpn configs, and deleted the \ from the end of the line.
