Anyone? Nextcloud is completely unusable like this… thanks.

I’ve fixed this.

  1. Open Terminal
  2. Run “/Applications/nextcloud.app/Contents/MacOS/nextcloud --logfile ~/nextcloudlog”
  3. Open the logfile “nano ~/nextcloudlog”
  4. Go to the bottom of the file using “ctrl + _” then “ctrl + v”
  5. Found the below error in the log:
07-12 11:05:23:103 0x7fed2a650bb8 _csync_detect_update: file: .Spotlight-V100, instruction: INSTRUCTION_NEW <<=

07-12 11:05:23:127 1884838 OCC::SyncJournalDb::commitTransaction: No database Transaction to commit
  1. Added “.Spotlight-V100” to the “ignore” list and it’s running again.

Be nice if the app told me which file was causing the issue, rather than giving me an unhelpful message saying something failed.

I had the same problem with Mac. Solved it with not using “.” in folder- & filenames.
I had the issue with the name “versch. Objekte”
