{0} communication error. Please check port number

[bmw]

This started to happen all of a sudden. This account using ZDesktop is my main Zimbra Collaborative Suite account. Thoughts? (I changed the domain and filename in question to something fictitious.)

"{0}" communication error. Please check port number. (debug info)

Debug message: Unbuffered entity enclosing request can not be repeated.

Exception:

Hey bmw,

A bit relieved to see you with my same issue, i have been following up this with multiple threads and could get some breakthroughs. This has been reported as recurring issue with zdesktop 1.x. I have an information that ZD beta 3 (thanks to phoenix) can be of help to solve this problem.

I know it has been a long time but still have you tried ZD beta 3? Anyways good to see you
