Re: Cauldn't find CALDAV or CardDAV service

Hi, I have the same problem since I updated my mobile phone to android 7. My cardDAV-server runs on a synology diskstation. Does anyone have an idea to solve the problem?

The connection to 192.168.1.100:8008 has timed out. This is probably a networking/server problem. You may try to reach the server with your mobile device’s Web browser first.
