I donât have site-available instead I have site-enabled
In a properly installation, nginx conf is in sites-available. Doesnt matter. Display nginx.conf please
Your nextcloud site is accessible right ?
Is there sth in sites-enabled?
I donât know how to copy the content from the config file in vi. Sorry 
Yes I can login with chrome into nextcloud. If I try to log in with my new fairphone3 /e/OS it is not possible. It also gives me a caldav and carddav error.
in sites-enabled there is just one file calendar-nginx.conf
You need to find the right config file. I dont think that nginx.conf is the right because you dont need to change server_name or root directives if your site works.
Your right config contains the following lines :
server_name yourdomain ;
root pathToYourNc;
where pathToyourNc is the right path (/var/www/nextcloud or /var/www for ex).
This file exists because your NC site is accessible.
If your installation use Docker, so I dont think that Nginx is your http server. Nextcloud docker contains apache server. Look at this :
https://hub.docker.com/_/nextcloud/
Ah, so because it is in the docker it is not connected to the rest of my nas. (sorry I try to simplify the terms 
)
I looked inside the docker an saw this, so I imagine it is really working on apache an not nginx.
My Instalation is in Docker/nextcloud folder, but I think that the nextcloud folde is the root folder of the webserver.
and inside the config folder
So what config do I need to change and how?
and inside the config.php
<?php $CONFIG = array ( 'htaccess.RewriteBase' => '/', 'memcache.local' => '\\OC\\Memcache\\APCu', 'apps_paths' => array ( 0 => array ( 'path' => '/var/www/html/apps', 'url' => '/apps', 'writable' => false, ), 1 => array ( 'path' => '/var/www/html/custom_apps', 'url' => '/custom_apps', 'writable' => true, ), ), 'instanceid' => 'oc22swys51ev', 'passwordsalt' => 'KCfCx34tPgAOPuZKXZ6I3rURt2vGBR', 'secret' => 'gyeJ0XZ33rZnVy4SchcOwwtoZJRDoC/hnx6iUnCOVKHT9Wit', 'trusted_domains' => array ( 0 => 'mydomain:PORT', ), 'datadirectory' => '/var/www/html/data', 'dbtype' => 'mysql', 'version' => '19.0.0.12', 'overwrite.cli.url' => 'http://mydomain:PORT', 'dbname' => 'nextcloud', 'dbhost' => '192.168.xxx.xxx:3306', 'dbport' => '', 'dbtableprefix' => 'oc_', 'mysql.utf8mb4' => true, 'dbuser' => 'USER', 'dbpassword' => 'PW', 'installed' => true, 'ldapIgnoreNamingRules' => false, 'ldapProviderFactory' => 'OCA\\User_LDAP\\LDAPProviderFactory', ); Sorry for the bad formating of this code.Your last screen suggest that your config is in /etc/apache2/sites-available
this is âonlyâ the config from the php app that we call nextcloud. but this has nothing to do with the web serverconfig you are looking for.
would you mind to run a ls -la in docker/nextcloud because there should be a .htaccess with the following line.
https://github.com/nextcloud/server/blob/8325ab4bf05494f8c54d226784a55c0988e30f88/.htaccess#L68
If I navigate to usr/local/etc/apache22 I only see the folder site-enabled. Iâm again at the wrong palce, or?
Reiner_Nippes is right, you can edit a .htacess in your nextcloud directory. Sorry to not think about that, I have nginx and there is not .htacess in nginx.
Yes itâs the right .htacess file config
Ok I did some changes in the htaccess but I still get the message that my webserver is not configured properly.
To be honest I donât know if I modified the .htaccesse properly.
my domain is, https://mydomain:PORT
how do I post my .htaccess content? The format is strange
Oh yes, I managed to get rid of these error but only for caldav. The carddav is still not working.
Iâm not realy sure why but I will finde out soon, hopfeully.
Thanks for the help!!
Everything works fine, now. I made a mistake for the carddav link.

Finally Iâve found the solution.
You have to edit file .htaccess located in docker/your_nextcloud_folder.
Under <IfModule mod_rewrite.c> you have to edit just 2 strings:
RewriteRule ^\.well-known/carddav /remote.php/dav/ [R=301,L]
RewriteRule ^\.well-known/caldav /remote.php/dav/ [R=301,L]
It should looks like this:
RewriteRule ^\.well-known/carddav https://your_site_address/remote.php/dav/ [R=301,L]
RewriteRule ^\.well-known/caldav https://your_site_address/remote.php/dav/ [R=301,L]
Iâm not sure, but after editing you may have to restart Nextcloud container.
Sorry for my English.
