Can't add .ics to Google Calendar - Nothing Happens - Keeps asking for URL

[Craig Solomon]

I go to add the calendar link to Google Calendar

https://trello.com/calendar/<<redacted>>.ics and nothing happens. 

See image below..  copy/paste, click add calendar, it blinks away.. and I can do it over and over w/o a different result (insanity) 

Anyone? Help?

I think, the problem is related to Google. Here the URL is accepted by, Google adds a new calendar, but doesn't display anything.

Adding a Trello-Calendar to Thunderbird works fine.
