Importing Feeds – feed not providing valid data

I’m trying to import 2 google calendars into the All-in-One Event Calendar. Both are under the same google account. However 1 imports fine, the other returns the error “The provided feed didn’t return valid ics data”. The two links are:

This one does NOT work properly: https://calendar.google.com/calendar/ical/0e2itup4uqgj2fh64hdnlna9kc%40group.calendar.google.com/public/basic.ics

This one works fine:
https://calendar.google.com/calendar/ical/d7ugtu8etg3imslnltiavmv3o4%40group.calendar.google.com/public/basic.ics

Thanks for any help.
