Okay found the Error. NextCloud rejects the authentication on CardDav and CalDav.
==> z-push/z-push.log <==
11/07/2017 16:07:52 [22531] [ERROR] [user@domain.de] BackendCardDAV->Logon(): User 'user@domain.de' failed to authenticate on 'https://127.0.0.1:443/carddav/addressbooks/user@domain.de/':
11/07/2017 16:07:52 [22531] [FATAL] [user@domain.de] Exception: (AuthenticationRequiredException) - Access denied. Username or password incorrect
And this is what NextCloud tells me:
Exception: {"Message":"HTTP\/1.1 401 No 'Authorization: Basic' header found. Either the client didn't send one, or the server is mis-configured","Exception":"Sabre\DAV\Exception\NotAuthenticated","Code":0,"Trace":"#0 [internal function]: Sabre\DAV\Auth\Plugin->beforeMethod(Object(Sabre\HTTP\Request), Object(Sabre\HTTP\Response))\n#1 \/usr\/local\/lib\/owncloud\/3rdparty\/sabre\/event\/lib\/EventEmitterTrait.php(105): call_user_func_array(Array, Array)\n#2 \/usr\/local\/lib\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Server.php(446): Sabre\Event\EventEmitter->emit('beforeMethod', Array)\n#3 \/usr\/local\/lib\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Server.php(248): Sabre\DAV\Server->invokeMethod(Object(Sabre\HTTP\Request), Object(Sabre\HTTP\Response))\n#4 \/usr\/local\/lib\/owncloud\/apps\/dav\/appinfo\/v1\/caldav.php(88): Sabre\DAV\Server->exec()\n#5 \/usr\/local\/lib\/owncloud\/remote.php(165): require_once('\/usr\/local\/lib\/...')\n#6 {main}","File":"\/usr\/local\/lib\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Auth\/Plugin.php","Line":188,"User":false}
Can anyone help me with this?
