Nginx Reverse Proxy Doesn't Serve Images Or CSS

I'm running a wordpress docker instance on server 192.168.1.105:4444. On a separate server on my LAN I have nginx acting as a reverse proxy pointing my domain to it. I am able to load html, but images and css are not loading. There are many posts about this error, but it seems like there can be many things that cause this error specifically. I would appreciate someone reviewing my config for errors:

Here's my config file so far.

server {
  server_name  test1.example.com www.test1.example.com;

  location / {
    proxy_pass  http://192.168.1.105:4444;
#   proxy_set_header    X-Real-IP           $remote_addr;
#   proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
#   proxy_set_header    X-Forwarded-Proto   $scheme;
#   proxy_set_header    Host                $host;
#   proxy_set_header    X-Forwarded-Host    $host;
#   proxy_set_header    X-Forwarded-Port    $server_port;

 }



    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/test1.example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/test1.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 ($host = www.test1.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = test1.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


  server_name  test1.example.com www.test1.example.com;
    listen 80;
    return 404; # managed by Certbot




}

Note: the commented section is troubleshooting that I have tried based on this tutorial: link

If I remove the comments the error becomes "refused to connect" and the url in the browser redirects from test1.example.com to test1.example.com:4444
