How Under local ubuntu 20.04 ro install nginx with Virtual Host Configs?

Under local ubuntu 20.04 I have appache2 installed and used and I want install nginx and and to switch them on need.

I switch to nginx with commands :

sudo systemctl disable apache2 && sudo systemctl stop apache2
sudo systemctl enable nginx
sudo systemctl restart nginx

to set 2 laravel apps using Virtual Host Configs. I edited nginx.conf :

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;


    gzip on;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

and 2 files for my sites /etc/nginx/sites-available/Laravel9TestWithNginx.conf :

Also I Created 2 links with commands:

sudo ln -s /etc/nginx/sites-available/Laravel9TestWithNginx.conf   /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/AdsBackend8.conf   /etc/nginx/sites-enabled/

So I have :

root@hoster-os:/etc/nginx/sites-enabled# ls -la
total 8
drwxr-xr-x 2 root root 4096 Apr 20 16:40 .
drwxr-xr-x 8 root root 4096 Apr 16 09:21 ..
lrwxrwxrwx 1 root root   43 Apr 20 16:40 AdsBackend8.conf -> /etc/nginx/sites-available/AdsBackend8.conf
lrwxrwxrwx 1 root root   53 Apr 20 16:40 Laravel9TestWithNginx.conf -> /etc/nginx/sites-available/Laravel9TestWithNginx.conf

In file /etc/hosts I have added lines:

192.168.55.164   local-laravel9-test-with-nginx.com
192.168.55.164   local-ads-backend8.com

I am not sure actually, is "192.168.55.164" nginx ip which I can use under ubuntu ?

I have empty /etc/nginx/conf.d/ subdirectory, as 2 config files are located in /etc/nginx/sites-available/ ...

But restarting the server :

systemctl restart nginx

I did not find any errors under /var/log/nginx...

What is wrong in my config and how to run my site ?

Thanks in advance!
