outlook iCal link not being accepted in grafana oncall schedules

[naaaaaates]

What went wrong?

What happened:

• one of our schedules stopped updating. It previously was reading calendar items from an ical without issue in order to fill a schedule in grafana. I tried to refresh the configuration and it was telling me : Ical url primary: Ical parse failed

Other calendars are working just fine and they are seemingly set up identically. Generating a fresh secret ical link still doesn't fix it.

What did you expect to happen:

• ical link should work to link to a shifts scheudle...

How do we reproduce it?

1. In our tassat.grafana.net tenant there is a Win Oncall schedule. The ical link in there was working previously but now it's not.
2. If you try to update that configuration or paste a new ical link for the same calendar, it gives the error from above.
