I'm trying to integrate autossh on a raspberry pi.

if I launch the command by itself

autossh -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" -N -R 22002:localhost:22 user@myserver

everything works fine, but launching the same command from systemctl

[Unit]
Description=AutoSSH tunnel service Remote port 22002 to local 22
After=network.target
[Service]
Environment="AUTOSSH_GATETIME=0"
ExecStart=/usr/bin/autossh -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" -N -R 22002:localhost:22 user@myserver.com
[Install]
WantedBy=multi-user.target

returns

Jun 25 13:43:22 pi autossh[995]: Permission denied, please try again.
Jun 25 13:43:22 pi autossh[995]: Permission denied, please try again.
Jun 25 13:43:22 pi autossh[995]: Permission denied (publickey,password).
Jun 25 13:43:22 pi autossh[995]: ssh exited with error status 255; restarting ssh

I am able to ssh my server without password from my pi.

The log in /var/log/auth.log gives me this

Ok found it, I simply had to add the user, because the key is for the user and systemd runs as root

[Service]
User=myuser
