Nginx port for

I have a node application that uses websockets. I’m using a custom
file like this. However, when I post to the application, the post isn’t
appearing in the client side of the application. Since it’s using
websockets to communicate between client and server, i’m wondering if I
a problem with the port numbers. You can see in my config that the
server is
listening on 80, but the proxy_pass is set to localhost:3000. Should
numbers be the same? if so can I set Nginx to listen on 3000?


server {
listen 80;


location / {
    proxy_pass http://localhost:3000;
    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;

The nginx configuration provided is valid for this use case. Ensure that
the browser is attempting to connect to the domain on port 80 for the
socket io stuff and ensure that socket io is listening on the same port
along with the node app.
