cannot connect workspace through tunnel

I have opened a tunnel to my desktop pc so that I can connect via “ssh glaser@localhost -p 3306”.
In VISPA I jused the settings: Host: local:3306, login:glaser

When I try to connect I get a empty alert in the web browser and the following debug output:

2014-04-03 14:51 - DEBUG - vispa.workspace - close transport
