Regarding auto-discovery: have a look into our manual here for creating well-known paths or SRV/TXT records:

It can make things really easy for users 🙂
http/2 and mail.de not working with DAVdroid 1.0.8
-
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:LOGS: 2016-05-07 10:30:41 1 [ui.setup.DavResourceFinder] Finding initial carddav service configuration 2016-05-07 10:30:41 1 [ui.setup.DavResourceFinder] No principal found at user-given URL, trying to discover 2016-05-07 10:30:41 1 [ui.setup.DavResourceFinder] Looking up SRV records for _carddavs._tcp.mail.de 2016-05-07 10:30:41 1 [ui.setup.DavResourceFinder] Found carddav service at https://adressbuch.mail.de:443 2016-05-07 10:30:41 1 [ui.setup.DavResourceFinder] Trying to determine principal from initial context path=https://adressbuch.mail.de/.well-known/carddav 2016-05-07 10:30:41 1 [HttpClient$1] --> PROPFIND https://adressbuch.mail.de/.well-known/carddav http/1.1 2016-05-07 10:30:41 1 [HttpClient$1] Content-Type: application/xml;

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-1-0-8So can we expect the issue will be solved by bitfire in the next releases?
regards

Please follow up in nginx HTTP/2 incompatible with okhttp.
