installed ZD 2.0 (build 10580) and want to sync an calendar via an remote
calendar (ical ics-file) does not work
I always get the error/message:
Critical: ! The following URL ist not currently reachable:

When i import the remote calendar (exactly the same url) via ZD-Preferences/Import:
File: http://<remote-server/.../cal.ics
Destination: Calendar -> Choose Calendar <xyz>
Clicking [Import] Button
does work ok and fine -> Import succeeded

Any ideas/hints how to solve that?

Thx ...
