Cannot connect to calendar or addressbook server HTTPChannel unhandled error

Question

Experiencing the dread OS X server 3.2.1 upgrade death.  I reinitialized the postgres DB and it finally started, but Calendar and Addressbook appear corrupted.  I've given up on trying to recover data, I just want the two services reinitialized.
I tried moving /Library/Server/Calendar and Contacts/ out of the way and restarting.  That seemed to help, but I still can't connect to it, including on the web port directly.
The error I see in /var/log/caldavd/error.log is:  (And no, I don't know Python well enough to trace through the program from this error):

Answer 1

Hi,
same here. After updating, calendar and contacts didn't work (which is by the way the sole reason why I have this server. Thanks to the attempts to force users into iCloud a few months ago)
I got a "CalDAVAccountRefreshQueueableOperation" error. I tried this
How to fix iCAL-Server Error: CalDAVAccountRefreshQueueableOperation
...but it didn't work, because the calendar was stuck on "Starting..."
So today I also rolled the server-app back with the TimeMachine. Starting server afterwards took forever - it looked like the upgrading-window ("server on this mac is updating") and the progress-bar didn't move for an hour or something. But then it moved, I got a weired error message, that something went wrong ("while updating service data an error occured"), but at least now it's running again.
Hope they fix this soon... For the future, I think I will go back to my old habit when I was a windows user and wait with upgrading running systems.
