I am syncing my contacts via davdroid with an owncloud server which is only reachable by its IP address. For this server there is a certificate with the IP-adress as CN. That worked well up to davdroid 0.6.8. After upgrading from 0.6.8 to 0.6.10 sync always failes with the following message:
When I try to add my acount with davdroid 0.6.10 I get a message that the certifiate is not issued for my IP address.
