my UCS is running on a VM. To shrink the HDD size i copied the VM to another iSCSI drive. The restart worked fine and the server is on again. But 2 problems came up:
- The Thunderbird clients in the domain can’t sync the imap folder (error message is Timemout, ucs.xxx.xx not reachable). But sometimes they can. 1 or 2 times a day it works normal.
- Nextcloud folders in the domain have the same issue.
I tried to change the Thunderbird settings from name to ip address, just the same problem.
My mobile phone with k9 mail and nextcloud can sync complete without a problem. (But the phone is in a different network).
The UCS can be pinged with it’s name or ip address from any client. Http access to the management console works fine.
Do you have a suggestion for finding out what’s wrong?
The server is on the latest version 4.5.5 erata 737.
