Can´t access Calendar from iPhone

Hello, I just can’t get it to set up the calendar on the iPhone. I get an error message every time that the password is wrong.
I’ve already tried every possible url I could find on the internet. With port 443 without port only the server name or the entire url.

iPhone: 14 Pro Max iOS Version: 16.1.2
Nextcloud version (eg, 20.0.5): 27.0.2
Operating system and version (eg, Ubuntu 20.04): Cloudlinux
Apache or nginx version (eg, Apache 2.4.25): Litespeed 6.1
PHP version (eg, 7.4): 8.1

The output of your Nextcloud log in Admin > Logging:

No Log for that error

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

$CONFIG = array (
  'instanceid' => 'oc3x******',
  'passwordsalt' => '*****',
  'secret' => '***********',
  'trusted_domains' => 
  array (

  'mail_from_address' => 'max',

You should not try any address in internet, but the address of your Nextcloud server f.ex: (contacts)
and (calendar)

I hope, it will work on your device as well as on my Android device.

thats not working for me… i tried

A call of the address

in the iPhone browser is working?

yes, is working and is working too and redirects to

nice … I’m searching for the same error at the moment … My Nextcloud server is a new setup …

I can browse to https://cloud.domain.tld/ and can login from my phone … I’m also able to access https://cloud.domain.tld/.well-known/caldav/ or also …/cardav/ and it will redirect …

Also, when I integrate the calendar and my contacts on my macOS device it’s working smoothly.

The ony differencies to my setup is that I’m using android with Davx5 client …
