Some calendars not supported?

[lb3ne]

Edit:
After some investigation, there could be some issues elsewhere then ics...! The first calendar actually doesn't work (Mail sent to calendar owner), period. The other one works in Apple Calendar, but not in ics.

Not sure if this is a "valid" issue here, but this worked some months ago with ics-integration.

The links (http://www.ikstart.no/terminliste/subscribe this gives 404) and https://www.footballwebpages.co.uk/bolton-wanderers/calendar.ics?reminder=0 (the Bolton one works in Apple Calendar) was used to show football-matches, but now it only show invalid link, and a lot of noise in log:

============= ICS Integration Error ================

The logs could be in wrong order, but as shown, 9184 times last 24 hours...?

This two links works 100%: https://f1calendar.com/download/f1-calendar_p1_p2_p3_q_gp.ics?t=1608560562819 and https://ics.ecal.com/ecal-sub/5fc1835021058a957b8b458c/Tottenham%20Hotspur%20FC.ics. Not sure if that is relevant info, but the ics-installation works with some calendars.

"Denne feilen stammer fra en tilpasset integrasjon" = This error is from a custom integration, if Google couldn't translate...

Did I do anything wrong here?

Hi, I think you're right .. https://www.footballwebpages.co.uk/bolton-wanderers/calendar.ics?reminder=0 doesn't work that way.
if you run "curl https://www.footballwebpages.co.uk/bolton-wanderers/calendar.ics?reminder=0" you'll see that its actually a cloudfare protected website.
I'd suggest to download the ICS, store it in your HA installation and read it locally
