Contacts not synched with Android 4.4.2, DAVdroid 0.9.0.4 and OC 8.1.2 server
After having updgraded to DAVdroid 0.9.0.4 the contacts fail to synch. DAVdroid Exception Details is attached.error-report.txt
I mostly wonder about message “HTTP RESPONSE: http/1.1 404 Not Found”, but the url is correct and works with another tablet/smartphone.
Thank you in advance.
This is a known problem of OwnCloud. Please update to the latest version of OwnCloud and the OwnCloud Calendar/Contact app and/or try to get help at the OwnCloud forums.
