I'm trying to subscribe to a remote iCalendar file, e.g. http://ical.mac.com/ical/German32Holidays.ics or http://company.grouphub.com/feed/pro...roject_id=1234
So in the web client I go to "Calendar", "New Calendar", choose "Sync appointments from remote calendar" and enter the URL there. I then always get error messages like "The Following URL is currently not readable: http: ..." or "Appointments could not be retrived. MAke sure the following URL is a valid ICAL feed: http:// ..."
Any hints what I'm doing wrong?
