Any ideas on how to fix or at least diagnose what's going on? I am connecting to a MySQL database on a CentOS server using SSH. I have setup port forwarding using PuTTY and have run VNC, and all of this seems to be working fine as it does now seem to be connecting to the server where before I would get an error that it could not connect. Now however it just hangs on the Connecting to data source dialog and will eventually error out with "An error occurred while communicating with the data source. The connection to the data source might have been lost."
