SSH to VM from Kasm Workspace does not work behind Traefik

[dazbeattie]

I have recently updated to the latest version of Kasm to take advantage of the SSH Compute capabilities. I normally run Kasm behind a reverse proxy of Traefik. This is then linked to a FQDN to provide an external entry into the environment. Everything works great, except SSH. If I browse to the instance using the internal address, say 10.10.10.10, then connect via SSH to an internal VM, say 10.10.10.20, it all works. If I connect to the instance via the FQDN, say "kasm.example.com", then the SSH connection fails. I get the error: kex_exchange_identification: Connection closed by remote host on my VM

There is nothing in the user guides to show the how to configure this through Traefik
