I am having an issue with VNC connection on 1 server, and an SSH connection on 
another.  We have 2 other SSH connections that work fine.

For the VNC (which is running on RHEL 7 with TigerVNC), I see this in 
/var/log/messages:

For the SSH connection, I get prompted for the username and as soon as I enter 
it, I get the "Home/Reconnect" window and the log shows the following:
