Nextcloud 18.04: Kein Webdav, Caldav, Cardav

Hallo liebe Community,

ich bin verzweifelt face-sad

Seit Tagen kämpfe ich mit Nextcloud, was ich auf einer lokalen VM installiert habe. Ich kann aber leider nur die UI im Browser nutzen - Kein Webdav/Caldav/Cardav...

Der Testserver (Gast System):
  • Ubuntu 18.04 Server mit ISP Config
  • mehere Domains, u.a. die "nextcloud.test22.local"
  • Das VM System ist VirtualBox

Das Wirt System:
  • Hier sind der Einfachheit halber alle Domains des Testservers in der hosts - Datei eingebunden
  • OpenSuse Leap

Das Problem:
Kein Zugriff auf Webdav/Caldav/Cardav
  • Webdav: vergeblich mit Dolphin getestet, Zugriff wird verweigert
  • Caldav & Cardav: vergeblich mit Thunderbird getestet. Es erscheint immer wieder das Abfragefenster zu Benutzername&Passwort. Wenn ich die richtigen Daten eingegeben habe, erscheint es wieder und fragt ab. So geht das endlos weiter
  • Auch getestet: Der Nextcloud Desktop Client. Hier erscheint der LogIn Bereich. Dieser wird zur schwarzen Box wenn ich ihn anclicke. Einmal habe ich es so weit geschafft, daß ich Username+Passwort eintragen konnte. Das resultierte in einem endlosen Ladevorgang

Webserver Config (Apache)
  • Hier habe ich die PHP Modi Fast CGI sowie PHP-FPM getestet. Funktionierte beides gleich schlecht (siehe oben)
  • PHP Version 7.2

Die Host Datei wurde durch ISP Config automatisch erstellt und durch eigene Direktiven, entsprechend der Doku von Nextcloud, in der ISP Config UI ergänzt (das sind die am Schluss der Datei):

mehere Domains, u.a. die "nextcloud.test22.local"
Was eine sehr schlechte und nicht besonders intelligente Wahl ist ! Die Root Domain .local ist absolut Tabu und sollte niemals benutzt werden, denn sie ist weltweit dem mDNS Dienst vorbehalten durch die IANA.
https://de.wikipedia.org/wiki/Zeroconf#Multicast_DNS
bzw.
https://tools.ietf.org/html/rfc2606
Das es damit über kurz oder lang zu Fehlern und Konflikten im Netz kommt liegt dann auf der Hand. Öffentlich funktioniert diese Root Domain niemals und wäre ein noch größeres NoGo !
Welche Root Domains sinnvoll zu verwenden sind erklärt dir dieser ct' Artikel:
https://www.heise.de/select/ct/2017/26/1513540412603853
Lesen und verstehen hilft hier also wirklich !

P.S.:
In einer simplen Nextcloud Standard Installation gemäß:
https://bayton.org/docs/nextcloud/installing-nextcloud-on-ubuntu-16-04-l ...
funktiuonierte der Card-, CalDAV sowie der WebDAV Zugang ohne jegliche Probleme oder Zutun Out of the Box auf einem Ubuntu 18.04 in einer ESXi 6.7 VM.
Natürlich mit korrekter Root Domain und entsprechendem Regelwerk der Firewall.

Die anderen Domains funktionieren aber seltsamerweise als .local (inklusive webdav, caldav und cardav). Ich denke nicht daß es an der .local Domain liegt.

War auch nur ein kleiner und bescheidener Hinweis auf die falsche und nicht Standard konforme Verwendung dieser Root Domain. Auf einem öffentlichen Server immer ein klares NoGo !

Es ist wie gesagt eine VM, die nicht öffentlich erreichbar ist. Es ist mehr ein Entwicklersystem zum coden
