I am getting the "took too long to respond" timing out error in browser. There is an issue accessing the site on port 443 but there are no firewalls.

This is not the default server block. I have another site on SSL however that is an "external" cloudflare ssl.

No errors in nginx logs.

Here is the server block:

server {
       listen 80;
       listen [::]:80;
       listen 443 ssl;

       server_name mydomain.com www.mydomain.com;

      # return         301 https://$server_name$request_uri;

        error_log    /var/log/nginx/mydomain.com.error.log debug;

        root /var/www/mydomain.com/html;
        index index.php;

        set $cache_uri $request_uri;

    # POST requests and urls with a query string should always go to PHP
    if ($request_method = POST) {
        set $cache_uri 'null cache';
    }   
    if ($query_string != "") {
        set $cache_uri 'null cache';
    }

        ssl_certificate_key /etc/nginx/ssl/mydomain/mydomain.key;

        # Use cached or actual file if they exists, otherwise pass request to WordPress
    location / {
        try_files /wp-content/cache/page_enhanced/${host}${cache_uri}_index.html $uri $uri/ /index.php?$args ;
        }
