Including external calendar URL (webcal) isn't possible
I'd like to import an external nextcloud calendar: This one
If I download the ical-file by pressing the "Herunterladen" (download)-button in the top right corner, an add this to the "Include ICS File"-calendar, everything works fine. The new events are created in the sysfolder.
However, if I create a new external calendar with the URL
(see the link of the "Abonieren" (subscribe)-button), nothing will happen. But this link works fine with a google calendar.
When I start the sheduler "Updating external calendars (created by saving the calendar record) (cal)"
I get an error message:
Die Ausführung von Task "Updating external calendars (created by saving the calendar record) (cal)" ist fehlgeschlagen mit folgender Meldung: Could not write new md5 hash to database: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
Does anybody have any ideas?
