The issue you are facing:
I see 401s in my Apache access logs for WebDav transactions for “PROPFIND”, “REPORT”, and “OPTIONS” for seemingly all transactions, but especially iOS webdav (dataaccessd/1.0) and 2Do (2Do/3.8). Everything seems to be working as I am unable to discern any data that is corrupted/missing on the NextCloud side, however, I am concerned I am losing data due to the 401s.
Is this simply a case where Nextcloud doesn’t implement those WedDav/CalDav options? Is this a configuration issue?
Is this the first time you’ve seen this error? (Y/N): Y
