InvalidDavResponseException: Expected 207 Multi-Status, got 200 OK



  • I'm using Davdroid since a long time now and it had worked very fine. Recently sychronization stopped working and I get an InvalidDavResponseException (see below). This happens only for accounts on a Horde Server (v5.2.13). I didn't change the configuration and only kept DAVdroid up-to-date.

    The error appears for calender and tasks.

    I have another Android phone were sychronization still works with an old version of DAVdroid (3.x). Thus I tried to downgrade on my (first) phone but this did not fix the error.

    Next, I created a new DAVdroid account using the same settings as an existing account. The error message "Couln'd refresh collection list" appears.

    I could narrow down the steps to reproduce the error message to tapping on "refresh calendar list" in the CalDAV context menu in the account settings.

    Seems to be a server problem. Did you ask Horde support?



  • hmm, if it is a server problem, why the second phone still works?



  • ok, issue solved!

    It was a problem with Horde. I shared a calendar with another user who is on another server. Every time I clicked the calendar in the web interface, I was logged out. After a while the link to the problem described here came into my mind. Now problem is fixed.
