Why is there no redirect from http to https?

Question

Nginx

there are 2 sites, here are their configs

upstream node {
  server 127.0.0.1:8080 fail_timeout=20s;
}

server {
            server_name site1.com;
            return 301 https://$server_name$request_uri;
    } 

server {

    server_name site1.com www.site1.com;

    listen 443 ssl;
  ssl on;
  ssl_certificate /var/www/site1.com/ssl/certificate.pem;
  ssl_certificate_key /var/www/site1.com/ssl/key.key;

    ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers  "RC4:HIGH:!aNULL:!MD5:!kEDH";
    add_header Strict-Transport-Security 'max-age=604800';


    root /var/wwwsite1.com/public;
    index index.php index.html index.htm;

    rewrite ^/(.*)/$ /$1 permanent;
  
    access_log     /var/log/nginx/site1.com.access.log;
    error_log      /var/log/nginx/site1.com.error.log;

  location /ws {
    proxy_pass http://node;
    proxy_http_version 1.1;
    proxy_set_header Upgrade websocket;
    proxy_set_header Connection upgrade; 
    }

    location / {
        try_files $uri $uri/ /index.php?$query_string;
  
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
   
    location = /50x.html {
        root /usr/share/nginx/html;
    }
    client_max_body_size 300m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

and site 2

server {
            server_name site2.com;
            return 301 https://$server_name$request_uri;
    }

server {
    server_name site2.com ;  

    listen 443 ssl;
    ssl on;
    ssl_certificate /var/www/html/ssl/certificate.pem;
    ssl_certificate_key /var/www/html/ssl/key.key;

    
    root /var/www/html/public;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
   
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

}

if you type in https://site1.com , then everything works correctly, but if you simply insert site1.com into the browser line, it redirects to site1.com
PS: site1.com is launched via cloudflare

Answer 1

Ports must be specified:

server {
    listen 80;
    listen [::]:80;
    server_name site.ru www.site.ru;
    return 301 https://$server_name$request_uri;
}

Answer 2

You need to listen on port 80.
