Nginx reverse proxy issues for Pterodactyl

Question

I've been trying to create a dedicated VM to act as a reverse proxy using nginx's proxy_pass to route traffic to another host running Pterodactyl with nginx on it.

I have also set the following in .env config as required for running reverse proxy: TRUSTED_PROXIES=192.168.10.11 (my proxy vm) (ref application docs)

On VM running proxy (192.168.10.11) I have the following config: If I use the first config bellow I just get connection reset.

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

  server_name example.com;

  location / {
      proxy_pass http://192.168.10.30/;
  }
}

If I do redirects with ssl I get "err_to_many_redirects".

server {

  server_name gsp.networkgamez.com;

  location / {
      proxy_pass http://192.168.10.30/;
  }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


  listen 80;
  listen [::]:80;

  server_name example.com;
    return 404; # managed by Certbot


}

On the VM runnign the second nginx instance with Pterodactyl (192.168.10.30) the config I have is the default nginx config setup from the docs https://pterodactyl.io/panel/webserver_configuration.html#nginx (obviously with domain tags changed to my domain)

server_tokens off;

server {
    listen 80;
    server_name <domain>;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name <domain>;

    root /var/www/pterodactyl/public;
    index index.php;

    access_log /var/log/nginx/pterodactyl.app-access.log;
    error_log  /var/log/nginx/pterodactyl.app-error.log error;

    # allow larger file uploads and longer script runtimes
    client_max_body_size 100m;
    client_body_timeout 120s;

    sendfile off;

    # SSL Configuration
    ssl_certificate /etc/letsencrypt/live/<domain>/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/<domain>/privkey.pem;
    ssl_session_cache shared:SSL:10m;
    ssl_protocols TLSv1.2;
    ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';
    ssl_prefer_server_ciphers on;

        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param PHP_VALUE "upload_max_filesize = 100M \n post_max_size=100M";
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param HTTP_PROXY "";
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
        fastcgi_connect_timeout 300;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;
        include /etc/nginx/fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }
}

Does anyone have an idea of what this could be thats causing it? I have been tailing both the nginx access and the error log but it doesent generate anything.

Thanks in advance!

Solved by including https in the proxypass function

Example:

proxy_pass https://192.168.10.30/;
