Unable to add calendar to iCal (Calendar) on iOS and macOS

[Firesphere]

I've got the rewrites in my htaccess as such:

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
# iOS 7 (and later)
RewriteRule /.well-known/carddav /baikal/html/dav.php [R,L]
RewriteRule /.well-known/caldav /baikal/html/dav.php [R,L]
# Mac OS X 10.10
Redirect /.well-known/carddav /baikal/html/dav.php

Either Calendar keeps asking for my username/password, or it simply says "invalid response from {calendar server}"

I have no idea anymore, as to what I'm doing wrong, it works everywhere except on Apple things...

Nobody?

you use https? certificate is not self-signed and accepted by the browser?

[Firesphere]

Yes, the certificate is an Let's Encrypt certificate and accepted by the browser.

I've not yet been able to solve it, I'll have to look up the logs again.

Not sure whether this helps, but Apple keep tightening the requirements for certificates to be considered "trusted" by macOS, iOS, and friends (for instance [1] and [2]).
