[ARM Testing Update] 2023-03-30 - Phosh, Blender, Kernels, Thunderbird, Xorg-Server, KDE-git

Hi, I am experiencing an issue after the latest nexcloud (server) update.

I cannot connect from KDE PIM (Akonadi’s Webdav) anymore, it seems there are issues with authentication.
On the client side, Akonadi says that:

You are about to log in to the site "<my site>" with the username "<my user>", but the website does not require authentication. This may be an attempt to trick you.

Is "<my site>" the site you want to visit?

On the server side, I see this in the nextcloud logs:

    "File": "/usr/share/webapps/nextcloud/3rdparty/sabre/dav/lib/DAV/Auth/Plugin.php",
    "Line": 152,
    "message": "No public access to this resource., No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured, No 'Authorization: Bearer' header found. Either the client didn't send one, or the server is mis-configured, No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured",
    "exception": {},
    "CustomMessage": "No public access to this resource., No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured, No 'Authorization: Bearer' header found. Either the client didn't send one, or the server is mis-configured, No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured"

This only happens when I try to connect via WebDav from KDE-PIM.
From my mobile phone (DAV-x on Android) everything runs as smooth as usual.

(the nextcloud server runs on a Raspberry Pi 4, manjaro testing branch).
