Trick a Rails app to think about it on another port

I have a port-based Rails application 8080that I need to trick in order to consider it running on port 80.

I run Varnish on the port 80and redirect requests for nginx to the port 8080, but when the user tries to log in with OmniAuth, and the self-generating device creates the URL for redirection to the server, he thinks that it is on port 8080, which the user will then see.

Is there a way to trick a Rails application to hard-code a port like 80 (I would think that this is bad practice) or does nginx redirect the request as if it is running on port 80?

Since I am not starting the nginx proxy for the Rails application, I cannot think of a way to trick the port.

Has anyone encountered this problem before, if so, what configuration is needed to fix it?

Thanks in advance!

EDIT: Both nginx and Varnish are running on the same server.

I have the same setup with Varnish on port 80 and nginx on port 8080, and OmniAuth (no Devise) does the same. I tried to install X-Forwarded-Port, etc. In Varnish and fastcgi_param SERVER_PORT 80;in nginx, both without success. Another part of my setup is Passenger (which you didn't mention), but if you really use Passenger, you can use:

passenger_set_cgi_param SERVER_PORT 80;

( , http, , server.)

  if ( obj.http.Location ~ "^http://[^:]+:8080/.*" ) {

If you need to rewrite HTML pages, it will be much harder to do completely with varnish.
