I am having exactly the same problem. What information can I provide to help diagnose this?

I have just this week spun up the latest NextCloud docker release. It's a blank/fresh install. All I have done is install the Calendar and Contacts app, then tried to install the DAVx client on an Android device and I can't log in to the Nextcloud server from the DAVx client I get the same error:

Here is a screenshot from the client. If you don't speak German, it's just a generic error message which states there was an internal server error ("the server could not complete the request"), with the client IP and query ID.

I confirm exactly the same issue during registering new NextCloud Windows client. All previously registered clients are working fine, just new ones cannot be registered. Latest version 25.0.2 (upgrade) Debian Linux, Maria DB, Apache, PHP + FPM.

I faced this problem/bug today after changing my password, I'll describe my actions to overcome it although I'm not sure if they were really effective or if it was a self-solved bug:

I copied and opened the authorization link provided by the customer in the browser. After the first page it redirects to another page and I noticed that the URL had a GET "User=" argument (or similar, without the value). I put my user in front of it "User=myuser" and pressed the enter key. So I gave the permissions. After that, I opened the authorization link provided by the client again, followed the normal procedure and the client was authenticated.

Hope these steps help.

Client version 3.7.3 (Appimage) Nextcloud 25.0.3

Same issue on 25.0.4, so not backported yet?

Seems to be aclient issue as by the above comment. As it is true that argument 1 (User) is null. Which it must not be.

Backport up for v25.0.5: #36806 Would be nice if someone could verify this PR really fixes the issue.

Copied the backport over my 25.0.4 instance, tried to login with AntennaPod (GPodderSync-App), input fields for Username/Password were missing, but login with app credentials worked.

Did you clear the client/browser cache? Because a JavaScript file is responsible for enabling the login form.

MichaIng avatar Feb 28 '23 10:02 MichaIng

No, was on mobile Firefox. Tried with a private browsing window now, works.
