Dear all,

We are heavily struggling after we updated our Nextcloud from v21 to v27. Afterwards the Windows Nextcloud Clients cannot connect to our server anymore.
Even when I try to do a clean client setup, I can only enter the server URL. Afterwards the redirect or something like that doesn’t work:

Translated: Error while accessing the token endpoint: Error transferring https://our.server.com/index.php/login/v2 - server replied: Internal Server Error.

Accessing the Website via Firefox works flawlessly. Using the iPhone App works, too.

Of course, I have also uninstalled the Windows client and removed the Nextcloud folder in %appdata%… but the issue appears again and again . I have also tried to use the latest client. On the first start an import error appears:

Looks like the bug which was described here:

Any ideas?

The issue is solved: the table “nextcloud.oc_login_flow_v2” was missing. Therefore, the v2 login procedure didn’t work at all and caused those messages.
