Can't setup new account

[schulmar]

I want to setup Contacts and Calendar syncing with an NC12 on a Galaxy S4 running Android 5.0.1

After installing Davdroid version 1.64-ose from F-Droid I tried to add an account in App, entering my host https://my.nc12.host.example/remote.php/dav/ (or /webdav/ or no path at all, it doesn’t matter) and the correct username and password combination.

Then I get a popup labelled “Ressourcen Erkennung” that stays on forever.
When this popup comes up, I get following log entries on my Webserver:

192.168.0.73 - - [03/Aug/2017:12:52:27 +0200] "PROPFIND /remote.php/webdav/ HTTP/2.0" 207 624

These repeat about every two minutes.

Additionally, I can’t even create the account via Android’s settings accounts menu.
When I select either DAVdroid or DAVdroid CardDAV the screen gets reset to the accounts menu, so I can never even enter login information. Which makes me think something fishy is going on with DAVdroid or Android here.
Furthermore, I have several devices that connect with DAVdroid (1.6.3-ose) to this server without problems. However, they were set up quite a while ago.

Just got my hands on the corresponding log from the phone. You can find it at https://paste.fedoraproject.org/paste/9ixNaX2IXP4-4AwNAzqJYA

Does this still happen with 1.6.5? If yes, can you provide a test account so that I can have a look? (play@bitfire.at / direct message)

Both issues have gone away with 1.6.5-ose from F-Droid. Thanks for the update.
