Calendar sync results in Bad Request 400



  • I synchronize 2 calendars with my Posteo account. The synchronization does not work anymore for 1 month. The synchronization always results in the HTTP error 400 Bad Request.

    DAVdroid 0.8.0 from Play Store

    Android 4.4.4
    Samsung Galaxy Alpha (SM-G850F)

    Thanks a lot for your support!

    Is this related to recurring events, see #523?



  • No, I cannot see the same error message. The server does not respond a certain reason:

    D/Wire    (13260): http-outgoing-0 << "HTTP/1.1 400 Bad request[\r][\n]"
    D/Wire    (13260): http-outgoing-0 << "Date: Wed, 24 Jun 2015 10:15:34 GMT[\r][\n]"
    D/Wire    (13260): http-outgoing-0 << "Server: Apache[\r][\n]"

    However, it seems to be related to recurring events:

    Can you please verify that this only happens for recurring events? In this case, it would be a duplicate of #523.



  • I will check that.
