sample nginx config for reverse proxy

nginx-reverseproxy-example.com.conf

# replace all instances of example.com with your domain name.
# request the appropriate Letsencrypt SSL Cert and fix the cert paths appropriately.
# paste this in /etc/nginx/sites-available/ as "example.com.conf" (replace with your domain) and then symlink to /etc/nginx/sites-enabled/
# nginx -t and systemctl nginx reload.
# Replace target.example.com with the appropriate IP or target domain in the proxy_pass line.
# Good luck!
