nginx not serving site on cellular data connection

  • 772

I have a web server running nginx. If I access the website through a wifi connection, it loads the website. If I access it using LTE on my phone, it just shows the default "Welcome to nginx!" page

Here is my site config file:

server {
    listen 80;
    listen 443 ssl;
    server_name {mysite.com};

    root   /path/to/public;
    index  index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
        include   /etc/nginx/conf.d/php-fpm;
    }

    ssl_certificate /etc/letsencrypt/live/{mysite.com}/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/{mysite.com}/privkey.pem;
}

    That "Welcome" makes me suspect nginx is not reading the Host header in the request and the response is the default virtual host definition (which is the welcome message).

    Remove your default vhost, on debian should be:

    rm /etc/nginx/sites-enabled/default

    Then add default_server to your site vhost definition:

    listen 80 default_server;
listen 443 ssl default_server;

    Reload: nginx -s reload

    Test with curl:

    curl -H "Host: mysite.com" mysite.com
curl mysite.com

    The first request is sending the host header, the second does not. Both should return the same becase mysite.com is default now for ports 80 and 443 (one default_server for port).

    This is like a brute force method, a smarter way would be debugging the requests, if all is correctly set up this should not happen.
