url reproduce problem

https://calendar.yahoo.com/subscribe?ics=https://staging.sendcalendar.com/api/calendar/nzqdhtbmx88cfsm8k/icalfeed&name=sample:%20walking%20tours

what cause of problem? more importantly, need change solve it? have found no documentation online, , have not seen similar reports of issue.

since don't have answers solving problem post own strategy solving this, have nothing else go on @ point (taken comment above)

addevent.com providing service lets users subscribe arbitrary calendars using yahoo calendar, , have solved problem. making sure ...

  • we use same transfer protocol addevent (http vs https),
  • we respond using same, or similar, http headers addevent,
  • we have same set of fields in our ics payload addevent

... should able solve problem ourselves. edit answer again once have done report findings.
