Nginx Configuration for support of domain name without “www”

I have deployed a LEMP stack to Linode and purchased a Wildcard SSL Certificate.

Prior to installing the SSL Certificate, I could type in example.com.au OR www.example.com.au and it would bring up the same HTTP website.

After installing the SSL Certificate, I only successfully reach the website when I type in www.example.com.au

I’ve tried setting the server_name inside of the server blocks in the nginx configuration, however, it doesn’t seem to have any effect on it.

Here is my nginx configuration file.

Note – I’m deploying WordPress using docker

upstream php {
    #server unix:/tmp/php-cgi.socket;
    server php:9000;
}

server {
    listen 80;
    listen (::):80;
    server_name *.example.com.au;
    return 301 https://$host$request_uri;
}

server {
    listen 80;
    listen (::):80;
    server_name example.com.au; # <-- this doesnt help at all
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name *.example.com.au;

    ssl_certificate /etc/nginx/certs/bundle.crt;
    ssl_certificate_key /etc/nginx/certs/example.com.au.key;

    root /var/www/html;

    index index.php;

    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

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

    location ~ .php$ {
        include fastcgi.conf;
        fastcgi_intercept_errors on;
        fastcgi_pass php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~* .(js|css|png|jpg|jpeg|gif|ico)$ {
        expires max;
        log_not_found off;
    }
}

Does anyone have a solution? When I look at the request details in the network tab, I don’t see a “Host” header being sent when typing example.com.au in the URL bar of the browser… but it is present when I type in www.example.com.au

Thanks
