You could try (all in one line, no blanks at the mail-client-induced
line wraps):

ssh -o
HostKeyAlgorithms=ssh-rsa-cert-v01 at openssh.com,ssh-dss-cert-v01 at openssh.com,ssh-rsa-cert-v00 at openssh.com,ssh-dss-cert-v00 at openssh.com,ssh-rsa,ssh-dss
yourusername at yourhost

This should attempt to initiate an SSH connection using your regular
ssh client that tries to use the RSA host key the way X2Go does.

If that doesn't connect properly, it's a sign something's wrong with
your ssh server setup.
