connection refused

Recently we installed a certificate from Thawte.

Everything seems to start well. Tarantella webserver and tarantella. But when we try to login we receive the following error and we can't find any clue what is going wrong

Secure Global Desktop connection lost

The connection to Secure Global Desktop server has been lost. The error reported was:

Unable to connect: Connection refused

To reconnect, we suggest you restart your web browser and try logging into Secure Global Desktop again.

If problems persist, contact a Secure Global Desktop Administrator.

Any help would be appreciated
