MacBook Air Time Capsule Backing Failing - Cannot Connect to Server
Up until upgrading to Big Sur was Mackbook Air Time Capsule backup was successfully backing up to an external drive connected to my iMac. Since the upgrade, it cannot connect to the drive, failing with a Server connection error, when trying to "Use" the backup disk
There was a problem connecting to the server "Paul iMac".
The server may not exist or is unavailable at the time. Check the server name or ip address, ch3ck your network and then try again.
Then displays
Time Machine can't connect to the backup disk.
There was an error authenticating with provided username or password.
My iMac remains on Catalina as not able to be upgraded to Big Sur & backups work fine.
If I connect the external drive to my Mackbook it backs up fine, just not over the network.
- I have set up sharing settings for the disk to allow guest access as well as a specific user
- Reformated the external hard drive to recommended APFS format
- I can connect successfully from my Mac Book Air to the iMac & drive using the Finder go to server function.
Any suggestions?
Been patiently waiting for an Apple OSX fix to either Big Sur or Catalina, but again in the most recent releases of both, no change
