Can't get google calendar to subscribe to DDay.iCal feed

I keep getting the error "Cannot fetch Url" when I try to Add my iCal feed by url to google calendar. I created a handler (.ashx) in c# using the DDay.iCal nuget package. It returns a string of data. It works in Outlook and I have validated it using a few different ical validators. I searched through a forums and had to escape commas and some other settings but I am not able to get google calendar working.

Example return when you view the source

Here is the code I'm using to generate the event above.

DateTime aDate = Convert.ToDateTime(reader["ArrivalDateUTC"].ToString());
DateTime dDate = Convert.ToDateTime(reader["DepartureDateUTC"].ToString());
iCalDateTime end = new iCalDateTime(aDate.Year, aDate.Month, aDate.Day, aDate.Hour, aDate.Minute, aDate.Second);
iCalDateTime start = new iCalDateTime(dDate.Year, dDate.Month, dDate.Day, dDate.Hour, dDate.Minute, dDate.Second);

Event evt = cal.Create<Event>();
evt.Priority = 1;
evt.DTEnd = end;
evt.DTStart = start;
evt.DTStamp = start;
evt.IsAllDay = false;
evt.DTEnd.IsUniversalTime = true;
evt.DTStart.IsUniversalTime = true;
evt.Created = iCalDateTime.Now;
evt.LastModified = iCalDateTime.Now;                                                
evt.Class = "PUBLIC";
evt.Status = EventStatus.Confirmed;

List<string> categories = new List<string>();
categories.Add("iSchedule - Flights");
evt.Categories = categories;

DDay.iCal.CalendarProperty htmlProp = new CalendarProperty("X-ALT-DESC", html.ToString());
htmlProp.AddParameter("FMTTYPE", "text/html");
evt.Properties.Add(htmlProp);

evt.Description = Regex.Escape(description.ToString()).Replace(",", "\\,");
evt.UID = reader["FlightLegID"].ToString();
evt.Transparency = TransparencyType.Opaque;
evt.Location = reader["DepartureName"].ToString() + " (" + reader["DepartureId"].ToString() + ")";
evt.Summary = "Trip " + reader["Number"].ToString() + " Leg " + reader["FlightLegNumber"].ToString();

Any help would be greatly appreciated.
