[X2Go-User] SSH error with pyhoca-gui

I'm seeing a message saying "SSH Error" with pyhoca-gui when connecting to a CentOS 7 server. The message in /var/log/secure on the server is Connection closed by 192.168.20.12 port 36098 [preauth]

I can log in to the server using SSH, and I am able to connect using pyhoca-cli and x2goclient. The profile specifies a shared id_rsa key.

On the server: x2goserver-4.0.1.20-1.el7.x86_64

On the client: x2goclient-4.1.1.0-1.fc27.x86_64 python2-x2go-0.5.0.5-2.fc27.noarch pyhoca-gui-0.5.0.6-4.fc27.noarch pyhoca-cli-0.5.0.3-5.fc27.noarch

How can I tell what pyhoca-gui is doing differently/incorrectly?
