CalDAV sync broken in iOS12

Try this (and the according answers):

NC13: caldav + macos/ios issue, android works

What happens, if you visit https://example.xyz/.well-known/caldav ?

Or this:

NextCloud / MacOS / CalDav / Woes

@Nextcloud-User you solved it. I need 'Advanced Settings: and add the port number and cut up the url in two input boxes. Here for reference a screenshot of my working input: [43] Thanx all in this thread who contributed!

Good luck!
