At first I would use “https” instead of “webcal” as a protocol. Then I have in mind that the mechanism has changed how remote calendars are read and imported. As far as I remember it doesn’t happen instantly but with the next cron run. Finally the syntax of the calendar which you want to import seems to be corrupted:
Thank you for being helpful. I’m experimenting between HTTPS:// and WEBCAL:// So far no conclusion yet. Some calendars started working, and don’t know why. Not sure if the calendars are updated based on CRON schedule, or when the Calendar circle thing is rotating.
Also, there are some bug posts that might be the same issue I’m having:
I assume that the default Nextcloud cron job is used to refresh the calendar too. There’s a recommendation to run it every 5min now. Afaik, a warning is displayed when an interval greater or equal 15min is set in the latest versions:
The cron job running every 5 minutes doesn’t mean the calendar will be refreshed every 5 minutes. It just gets a chance to be refreshed. There’s a lot of jobs waiting to be processed, and the calendar job only checks if it has to process when it’s due (as I was saying, the default frequency is of one week).
