Reinstalled x2goserver, still no luck. This is logged in the session file on the client:

Hi.

I updated my Debian Wheezy servers today (packages.x2go.org in sources.list), after that I no longer can connect to the servers, I get this message when I try with x2goclient-cli:

channel 1: open failed: connect failed: Connection refused

If i try with x2goclient I get an error message stating something like "The server didn't reply with an expected encryption key type. It could mean that the server has been compromised".

I have no problem using SSH keys to start an SSH session to the same servers.

apt history looks like this:

Any ideas?
