Ah ok. Thanks for the tip.
Since I dont like sharing my private calendar in public, I tried to set it up without sharing the calendar.
{
url: 'webcal://cloud.linus-schuertz.de/remote.php/dav/calendars/Linus/linusics?export',
symbol: 'calendar-o',
auth: {
user: 'Linus',
pass: 'superstrongpassword',
method: 'basic'
}
},
This setup is working! :))
Thanks alot for help!
