http/2 and mail.de not working with DAVdroid 1.0.8

  • W

    Hi,
    after upgrading to 1.0.8, my connection to my mail.de calender/contacts were broken.
    I removed all the app data and app itself and after a clean install, I tried to add a new account using email/password of my (mail.de account).
    My problem looks quite similar to the one here.
    But I can’t force mail.de to modify their installation to shut off http/2 😞
    This is what I get:

    Hi,

    Since 3rd may, my mail.de accounts expired the same problem with DAVdroid.
    After successfully connected to mail.de calendar with Evolution under Linux, i get in contact with mail.de support team.
    They now deactivated HTTP/2 and the issue is solved temporary. Its no problem on mail.de side!

    They pointed to these bitfire threats:
    https://forums.bitfire.at/topic/1082/owncloud-9-nginx-syncing-stopped
    https://github.com/square/okhttp/issues/2506
    https://forums.bitfire.at/topic/1083/http-2-and-mail-de-not-working-with-davdroid-1-0-8

    So can we expect the issue will be solved by bitfire in the next releases?

    regards
