Sync on Zarafa failed since 0.9.1 update



  • I have a Nexus 5 with Android 5.1.1. There are 2 DAVDROID-accounts configured. The first sync calendar and contact with an onwcloud-server and the second sync a calendar with a zarafa caldav gateway. Since the update to 0.9.1 the second one has no successful sync finished. It is given the following error message from the debugging.

    [error] I/O exception during sync, trying again later - EXCEPTION:

    @bronic Hello, it seems like there's an unexpected end of stream, i.e. the connection is interrupted.
