Basically I can’t log to ownCloud with davdroid. It stays this way for minutes ( http://i.imgur.com/W7urx2h.png ) until I see this message: “I/O Error Socket is closed”.
It works if i try with other similar apps (like CalDAV-Sync). It also works on PC (GNOME/Evolution).
OwnCloud 8.1.1 on Arvixe
DAVdroid 0.8.3 from F-Droid
Android 5.1.1 (Cyanogenmod)
I also provided a test account
