Setting up Nginx(SSL) to reverse proxy to a wordpress site

I have Nginx with SSL installed on a digitalocean server and I want it to act as a reverse proxy to as wordpress site on different server. The wordpress install is not on a docker instance and does not have SSL also its hosted on port 8001. I am including an example of my config and what happens is the nginx url redirects to port 8001. So if I type domain.com to redirects to domain.com:8001 and gives me an ERR_SSL_PROTOCOL_ERROR

server {
    server_name domain.com www.domain.com;
    listen 80;

        # when the SSL is generated enable these lines and replace the example domain with yours
    listen 443 ssl http2;

   ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/domain.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

        location / {
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $remote_addr;
                proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://wordpressurl:8001;
    }
}
