title: Google Calendar can't subscribe to icalendar feed over https?
body: <p>Would someone happen to know if Google Calendar has some problems subscribing to iCalendar feeds served on a secure https-address?</p>
  
  <p>I'm developing a website running on an https-address that has an iCalendar feed that users can subscribe to. The feed works just fine in Outlook and iCal, but not in Google Calendar. When a user attempts to subscribe to the feed, they get the error message <strong>"Could not fetch the URL"</strong>.</p>
  
  <p>I suspected that there was something wrong with the feed or the generated iCalendar data, so I ran the .ics file produced through a number of validators, and they were fine. To rule out an error in the feed itself, I put the generated .ics file on the server, to see if a static file would work, and that failed in Google Calendar as well. Then I put the file on a completely different server behind a non-secure (http) url, and that worked!</p>
  
  <p>So I'm beginning to suspect that httpS is the problem. The server's certificate is valid, so that shouldn't be causing any trouble. Besides, the validators could access the feed (and the static file) just fine.</p>
  
  <p>This google groups discussion indicates that others are having similar suspicions: <a href="http://productforums.google.com/forum/#!topic/calendar/61-eUd-fyrg" rel="noreferrer">http://productforums.google.com/forum/#!topic/calendar/61-eUd-fyrg</a></p>
  
  <p>Problem is, the site HAS to run on over https, so I can't just switch to http to make the feed work.</p>
  
  <p>So, if anyone has any information confirming or contradicing my theory, or any ideas about what else might be causing these problems, I would greatly appreciate it.</p>
