The issue you are facing:
I have the desktop app installed on a few machines with open at startup where they all used to just log in automatically after a reboot. But now I’m getting lots of sync errors because I keep working on these machines and realise later the nextcloud wasn’t authenticated after a reboot and seems to require the browser authentication every time.
I’m using Version 3.2.1 (macOS).
Is this the first time you’ve seen this error? (Y/N):N
Steps to replicate it:
- Reboot any OS connected to Nextcloud server via Desktop app
