Faye middleware Rails + Nginx

[Tu Truong]

Hi,

I'm using Faye as Middleware, it works on my local machine without Nginx, but when i deploy it to server using Nginx it's always return error 400.

My application.rb

# config.middleware.use Faye::RackAdapter, {:mount => '/faye', :timeout => 25} do |bayeux|
#   bayeux.on(:handshake) do |client_id|
#     WebsocketService.monitoring("handshake", client_id)
#   end

# end

Last time i'm run Faye as a rack file with proxy_pass for nginx config. Any advise please ?

# This is old config i use for run Faye in port 9292 and it work fine.

location /faye {
    proxy_pass http://127.0.0.1:9292;
    proxy_http_version 1.1;
    proxy_buffers 8 32k;
    proxy_buffer_size 64k;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

Thank you so much.
