This looks "fine".

Then you should be able to figure out the difference between the two
servers easily enough. I assume that you have verified that ssh
connections work to both servers.

You can set the environment variable:
set XPRA_SSH_DEBUG=1
Before you start xpra from the command line, then you will be able to
see what SSH command line is used by xpra and you can run it by hand if
necessary. Doing that whilst also keeping an eye on the ssh server log
should allow you to figure out what the problem is.
