Let me explain our problem:

some of our android users (nextcloud app - newest) getting the login screen from nextcloud. again and again. If i retype username and password the account is still logget in but after a moment the login screen appiers again. This failure is since over 6 month, i might think i have opend a github issue, but idk, maybe not.

In nextcloud interface there are 2 notifications who pop up every 10 - 20 seconds:

Sabre\DAV\Exception\ServiceUnavailable: OC\User\LoginException: Nutzer deaktiviert (fatal - webdav)
and
OC\User\LoginException: Nutzer deaktiviert (error - no app in context)

it it mean the user was disabled. But the user can still log in via webinterface and via nc app, but in the nc app there is the loop with the login.

Hope anyone can help us. If you need more information, please ask for it, i try my best :)

Best Regards,

Philipp

Please add the error message to your initial post. Anything in the logs? Usually for setup issues https://help.nextcloud.com is the better place.

Edited the issue report because most of the information were hidden inside the signing status detail block.

I would try to delete the app tokens for the user. Login as user, go to settings, delete all devices and connect the devices again.
