Yes, you right, my mistake
But found problem why dont work our code.
We use nginx + php-fpm and variable HTTP_HOST in code
Config:
location ~ \.(html|php)$ {
rewrite ^(.+)\.html$ $1.php break;
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/lib/nginx/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
try_files $uri =404;
}

When enable http2 variable HTTP_HOST absent in phpinfo
If set fastcgi_param HTTP_HOST $http_host; in phpinfo():
_SERVER["HTTP_HOST"] no value
