I’ve tried it - still the same problem. But the number of successfully downloaded contacts has increased.
The contact in front of the exception is now a different one.
Any restart of the sync process causes downloading a few more contacts.
Davdroid is unable to contact with owncloud calendar.

As you can see in the logs, the TCP connections have been refused. This is a server or firewall problem and very likely not a problem of DAVdroid. Please contact your administrator, or if you are the administrator, fix the network problems.
