Additional information

To reproduce, the following could help, i created a dummy calender to subscribe to:

https://calendar.proton.me/api/calendar/v1/url/Z85iOPKmM6nZoeZa6FcbxfD1Ki3JtXEhTm7aBN1sUv2hs3JoaoKzTNcfMRBkhHv_L-vNYz5ek1fGECBgCHttKg==/calendar.ics?CacheKey=-T3wmDwWvjJYNjo6asUyyw%3D%3D

For anyone investigating, the error seems to occur here:

Hey, It looks like you were trying to connect to calendar api rather than the caldav version of protonmail, I dont think they have support for caldav https://www.reddit.com/r/ProtonMail/comments/yj0rev/caldav_support_for_calendar/
