Finally I’ve 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]
I’m not sure, but after editing you may have to restart Nextcloud container.
Sorry for my English.
