Time Capsule Connection Failed after update to Mavericks After I updating OS X to Mavericks, Time Machine backup stopped to work on Time Capsule. 


I am connected on internet through Time Capsule without problems
AirPort Utility indicators are green with no errors (as well as Time Capsule LED)
Time Capsule name is displayed in Shared in Finder
I didn't do any changes except for update to Mavericks


But Time Capsule connection fails:


"Connection Failed" is displayed if I select TimeCapsule name in Finder
If I click "Connect as…", error dialog says: "There was a problem connecting to the server …"
If I click "Backup now" on Time Machine, it says: "Backup Failed: The backup disk … is not available."
In my case a serie of rabid and chaotic experiments with restarts and erasing a plist fixed the issue. Steps I did were: 


Disabled TM Backup
Removed TimeCapsule from TM Backup Disk (this might not be necessary, you will not be able to add it again until it will start to work)
Saving a screenshot of Exluded paths in TM Options (just for the case)
Renamed /Library/Preferences/com.apple.TimeMachine.plist to *.bac
Restarted Mac
Restarted TimeMachine
Removed /Library/Preferences/com.apple.TimeMachine.plist and renamed the old plist back
Restarted Mac again
Added a TimeCapsule back to TimeMachine Backup Disks


Hopefully it started to work. I don't know which of the steps were necessary and which just desperate.
