I have hosted a domain in the Nginx on my EC2 server and used this configuration:

server {
    listen 80;
    listen [::]:80;
    server_name www.mydomain.sa mydomain.sa;

    # Redirect HTTP to HTTPS with www
    return 301 https://www.mydomain.sa;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name mydomain.sa www.mydomain.sa;

    ssl_certificate /etc/nginx/sslcert/mydomain.sa/mydomain.sa.crt;
    ssl_certificate_key /etc/nginx/sslcert/mydomain.sa/mydomain.sa.key;

    root /var/www/html/files/;
    index index.html;
    
    location / {
        try_files $uri $uri/ =404;
    }
}

When I access this domain using browsers like Chrome, Edge, Brave, etc., the domain loads without adding the https:// in the beginning, but when I search the domain in Safari, it shows this error:

I searched the internet for a solution but none of them works.
