https://xxx.xxxxxx.com/public.php/webdav/ [HTTP/2.0 500 Internal Server Error 1318 ms]

[asirinelli]

There is also the following error in the browser console (before the error 500 reported previously):

Error 401 on https://xxx.xxxxxx.com/index.php/apps/richdocuments/ajax/settings.php
with the following answer:

{"message":"Current user is not logged in"}

[asirinelli]

This was at the end a bug in my Caddy webserver configurate. The rewrite public.php/* -> public.php?* was not configured properly.
Sorry for the noise.

[virtualdxs]

For future users in the same boat:

    rewrite {
            r ^/nextcloud/public.php/(.*)$
            to /nextcloud/public.php?{1}
    }

Replace /nextcloud/ with your Nextcloud path.
