Nginx remove port number :8080 in the url

I am using apache and nginx on a ubuntu VPS. Apache has priority of port 80 as I host websites there.

I have a small nodejs app that runs on port 3000. In the dir for the weblink i have a .htaccess file that redirects to port 8080 (reverse proxy on nginx) but I still can't get rid of the :8080 on the end.

Here is my .htaccess file

Options +FollowSymLinks
RewriteEngine on 
RewriteRule ^(.*)$ http://example.org:8080/$1 [R=301,L]

Here is my nginx config

server {
  listen 8080;
  server_name example.org;
  port_in_redirect off;
  root /var/www/example.org/webapp;
  access_log /var/www/example.org/log/access.log;
  error_log /var/www/example.org/error.log;

  location / {
    proxy_pass http://example.org:3000;
    proxy_redirect http://example.org:8080/ http://example.org/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
  }
}

I have tried with/without port_in_redirect off; proxy_redirect http://example.org:8080/ http://example.org/;

and when I goto example.org it redirects to example.org:8080. Is there a way to have apache and nginx coexist without losing my apache sites on port 80?
