I am getting various errors, usually Error creating SSH Tunnel: connect EADDRINUSE 52.28.72.225:22 - Local (0.0.0.0:29715) or just connection timeout.

When I connect from e.g. Robot 3T using the same connection settings, it works fine. Disabling firewall and antivirus did not help. 

I was looking for older Compass version (it used to work before; but I haven't used compass in the last few months), but you don't offer older versions for download.
