IOS/MacOS clients not working with CardDAV/CALDav

Hi,

I have issues with MacOS and IOS iphone/ipad caclendar and addressbook not connecting. The addressbook will connect, but not contact is displayed and the calendar will fail with “Unable to verify account name and password”.
On macOS I have too the emClient which connects and syncs fine both way with CalDAV and CardDAV connections.

The O/S is openSUSE Leap 15.5
php 8.2
nextcloud Hub 9 V 30.0.0.14
macOS Ventura 13.7
IOS iPad 17.7
IOS iPhone 18.0.1

Following is my apache 2.4 nextcloud config:

Alias /nextcloud "/srv/www/htdocs/nextcloud/"
<Directory "/srv/www/htdocs/nextcloud">
    Options +FollowSymLinks
    AllowOverride All

    <IfModule mod_dav.c>
      Dav on
    </IfModule>

    <IfModule mod_headers.c>
      Header always set Referrer-Policy no-referrer
      Header always set Strict-Transport-Security "max-age=15768000; includeSubDomains; preload"
    </IfModule>

    SetEnv HOME /srv/www/htdocs/nextcloud
    SetEnv HTTP_HOME /srv/www/htdocs/nextcloud
</Directory>

<Directory "/srv/www/htdocs/nextcloud/data/">
  # just in case if .htaccess gets disabled
  Require all denied
</Directory>

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteRule ^\.well-known/carddav /nextcloud/remote.php/dav [R=301,L]
  RewriteRule ^\.well-known/caldav /nextcloud/remote.php/dav [R=301,L]
  RewriteRule ^\.well-known/webfinger /nextcloud/index.php/.well-known/webfinger [R=301,L]
  RewriteRule ^\.well-known/nodeinfo /nextcloud/index.php/.well-known/nodeinfo [R=301,L]
</IfModule>

Can anyone who got this working with the macOS and IOS native clients give me any hints/information what I am doing wrong
Thanks and Regards

I did more troubleshooting and found to get an error 405 (Method unknown) for well-known in the apache log.
How can I get around this error with any additional config, permissions, etc.
