Cannot connect to "http://<redacted>/service/soap/". Please check host/port and network connectivity.

No matter whether i use my servers internal IP address (no firewall inbetween) or my servers public domain name i get this error message in the latest zimbra desktop 2.0.1

Strange thing is it worked this morning with Zimbra desktop version 2.0. i was upgrading to test out the social networking tab for my client, but at this rate i wont be deploying desktop v2.0.1 until i can find out whats causing this issue

Any ideas would be great.

Ps i have already searched the forums and tried serveral different solutions to no avail. Plus my funambol server which connects to http://<server-ip>/service/soap works perfectly!! ArGGHH.
