      Workaround:

      In google Calendar, locate the event that is throwing this error (In this example the event is TV14), and do the following:

      • Click on it and press "Edit Event".
      • Click on Time-zone to set the time-zone to a time-zone in Google Calendar and save.
      • From calendar settings take the private URL of the calendar (iCal) and try to subscribe again.
