CalDAV connection on iOS devices

I updated nextcloud today to 14.0.3 and still the same problem


the array looks like this:
array (
0 => ‘cloud.pfadimorgarten.ch’,
),

Is that correct? What is the mechanism of this array?

I have just seen, sometimes I get another log entry. So there are two kind of logs wehen an iOS produces en error:
