Hi
I’m running owncloud 10.0.10.4, calendar 1.6.1
I already share my agendas with 2 thunderbird and 1 android phone with davdroid that I bought.
Now I get the message "no access possible to Caldav or Carddav on Davx5 2.2.3.1-ose installed for free from f-droid on a 2d phone
I customized connexion with “URL and user name”. Url is “https://www…/remote.php/dav/userid” where userid is my id
I filled Userid field with “userid” and password with my password connexion to owncloud.
I read a comment on play store saying that davx5/davdroid is not working with owncloud. Any idea ?
Thank’s
Please provide the logs from davx5 to see whats going on. Tutorials to get the logs should be online somewhere 
Everything is working perfectly now. The address you get to give DAVX is this : “https://www/folder whereowncloud is located/remote.php/dav/calendars/userid/calendar name/”
Now, you get to synchronize the name of the account in order to make the related calendar app display the calendar.
Enjoy.
