OLS panel can only use Port 22. I tried a custom port by changing directly in the SSH using CyberDuck and the OLS Panel. It has this error.
“Error: Failed to restart SSH service: Command '['systemctl', 'restart', 'sshd']' returned non-zero exit status 1.”
This can easily be done in the other panel. You need to reuse Port 22 to open the SSH.
