webcal link not https

[Maggi68]

Hello,
I tried the app for my Test Homepage with a Calendar component at Joomla 4.4, called DPcalendar. There is a option to subscribe to a webcal link for each calendars. See https://j4.gfg-fortbildung.de/index.php/veranstaltungen#year=2023&month=11&day=5&view=month
Open the triangel above the calendar view and select "abbonieren".
If I copy this link it is like this webcal://j4.gfg-fortbildung.de/index.php?option=com_dpcalendar&task=ical.download&id=44
And it open a dialog to open a calendar app like Thundebird at my Windows PC. If I use a Android phone with installed ICSx5 a dialog window opens and the link will be displyed at the app. But than it is not a webcal link, now it is a http url link: http://j4.gfg-fortbildung.de/index.php?option=com_dpcalendar&task=ical.download&id=44.
But without https only http, so the link doesnot work.
Is their a solution to solve this problem?
Thanks

webcal is not a valid URL protocol, is kind of a way of stating that the link leads to a webcal link. Actually, webcal means http, and webcals https. So it should work perfectly.

It looks like the URL you are using expects https, so you can simply use the link https://j4.gfg-fortbildung.de/index.php?option=com_dpcalendar&task=ical.download&id=44. It should work correctly.
