I have several users running zimbra desktop (version 7.2.5) and most of them have no issues. We are connecting to a zimbra server (Version 8.6.0) running on CentOS in a VM.
I have had one user that has been getting this error occasionally: "Cannot connect to server". Clicking on the details shows "EMPTY RESPONSE"...
I can kill the zimbra process and re-launch it and everything is ok for a while, but then it happens again. Usually once or 2x a day.
This morning, I had one other user who had the same problem (so far just one time).
What should I be looking for?
This is causing me to pull my hair out.
