Failure communicating with remote server. Please try again later.

[John Reimer]

I have been using Zimbra Desktop 2.0 with no issues for a couple of months. Lately I have been getting a sync error, and the icon showing the status of the sync stays as an exclamation mark.


The following is the debug info:
Failure communicating with remote server. Please try again later.

I resolved the issue, though I still don't know the cause, and what really fixed it. What I did was install 2.0.1, and then reset the account.

It know shows the sync back online.

So, I don't know if it was the upgrade that fixed the issue, or the fact that I reset the account that fixed it. If anyone knows that would be great.
