I have problem with start page message about nginx misconfigure

Im sorry, but Im confused with this starting message about nginx misconfigure.
(I have just installed CakePHP 4)

Here is my nginx config:
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html/myServApp;
index index.php;
server_name _;
access_log /var/www/html/myServApp/logs/access.log;
error_log /var/www/html/myServApp/logs/error.log;
location / {
try_files $uri $uri/ /index.php$args;

location ~ \.php$ {
     try_files $uri =404;
     include fastcgi.conf;
     fastcgi_split_path_info ^(.+?\.php)(/.*)$;
     set $path_info $fastcgi_path_info;
     fastcgi_param PATH_INFO $path_info;
     fastcgi_index index.php;
     fastcgi_pass unix:/run/php/php8.1-fpm.sock;


location ~ /.ht {
deny all;

And yes, I have seen the help link from the start page ( Installation - 4.x ). I see no difference.

Maybe someone already met this issue ?
Maybe I was wrong with something?

Point your root to the webroot folder, not the folder where src etc. is positioned.

root /var/www/html/myServApp/webroot;

Thanks a lot, you ve save me again.
