/service/soap connectivity error

[sanbar]

Hi All,

I am using zimbra 6.0.9 GA Open source edition as my mail server. I have recently updated my Zimbra destop client to 2.0. I have started getting a connectivity error in my Zimbra desktop client which says :

Cannot connect to "https://mydomainname/service/soap/". Please check host/port and network connectivity

I am not able to figure out the root cause as all my deatils in the configuration page of Zimbra client is ok and it was working fine earlier. Please suggest.
