Google Calendar iCal feed setup question

Google Calendar iCal feed setup question

 I am trying to add a Zoho Creator ical URL to Google Calendar without success. 

In Google Calendar I go to Add/Add by URL then paste in the following ical URL and select 'Add Calendar'.  I get the following error...."Failed to add imported calendar at https://creatorexport.zoho......... for user@gmail.com"

I followed the ical feed steps at http://help.creator.zoho.com/iCal-Feed.html

My Zoho App is private, so I selected the link that adds in the encrypted code.

I've tried two versions of the URL. 

1.  With the encrypted code before the ical properties:  (some of the encrypted code is omitted from this post).

https://creatorexport.zoho.com/camillajeffs/appname/ical/Deadlines/84QA3VA7T.......edthp1j8/ZC_SET:ORGANIZER=Zoho&DTSTART=Start_Date_Time&DTEND=End_Date_Time&SUMMARY=Description&ZC_FULL_DAY_EVENT_VAR=All_Day_Event

2.  With the encrypted code after the ical properties: 


https://creatorexport.zoho.com/camillajeffs/appname/ical/Deadlines/ZC_SET:ORGANIZER=Zoho&DTSTART=Start_Date_Time&DTEND=End_Date_Time&SUMMARY=Description&ZC_FULL_DAY_EVENT_VAR=All_Day_Event/84QA3VA7T......hp1j8

I'm including a screenshot of the View in case that will help.

Could it be a URL length restriction?  My final URL with the encrypted code is 285 characters?

What am I missing?

Thanks.
