Nginx – how to display $ in bash script

I have a script. I can’t print $ in a screen.

#!/bin/bash

SERVER_IP=""
PASSWORD=""
DOMAIN=""
CONFIG_CONTENT=$(cat << EOF

server {
    listen 80;
    listen [::]:80;

    root /home/webmas/$DOMAIN;

    index index.php index.html index.htm index.nginx-debian.html;

    server_name $DOMAIN;

    location / {
            try_files $uri $uri/ =404;
    }

    location ~ .php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    }

    location ~ /.ht {
            deny all;
    }
}

EOF
)

ssh -tt -p 300 webmas@$SERVER_IP << EOF

mkdir $DOMAIN
cd /etc/nginx/sites-available
echo -n "$PASSWORD" | sudo -S sh -c "echo '$CONFIG_CONTENT' | tee /etc/nginx/sites-  available/$DOMAIN >/dev/null"

EOF

$uri is not displayed on the screen

I don’t understand why $ don’t help. Single quotes didn’t help either. I’ve run out of ideas.

    Try this answer using double quotes around the HERE documents:

    #!/bin/bash

SERVER_IP=""
PASSWORD=""
DOMAIN=""
CONFIG_CONTENT=$(cat << "EOF"
server {
    listen 80;
    listen [::]:80;

    root /home/webmas/$DOMAIN;

    index index.php index.html index.htm index.nginx-debian.html;

    server_name $DOMAIN;

    location / {
            try_files $uri $uri/ =404;
    }

    location ~ .php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    }

    location ~ /.ht {
            deny all;
    }
}
EOF
)

ssh -tt -p 300 webmas@$SERVER_IP << EOF

mkdir $DOMAIN
cd /etc/nginx/sites-available
echo -n "$PASSWORD" | sudo -S sh -c "echo '$CONFIG_CONTENT' | tee /etc/nginx/sites-available/$DOMAIN >/dev/null"
