Connection Failed

Hi,

I am running TC 3.1.1 (Build 6828) on a Win2K8 box and I regularly have a "connection failed" error when TC tries to connect to our SVN server.
The error I got is "svn: Cannot connect to 'svn+ssh://USER@MYSVNSERVER': Sorry, this connection is closed."

I got the error almost every day now. What is strange is that if I change the server DNS name with its IP address it will work for a day, and then I got the same error.

I have attached a screen shot of the error and below is the details of the error:

jetbrains.buildServer.vcs.VcsException: Checking changes for checkout rule '.=>.' failed with erorr: Cannot request dated revision from svn: svn: Cannot connect to 'svn+ssh://TCACCOUNT@SVNSERVER': Sorry, this connection is closed.
