Don't work in production mode

[aabse]

Hi.
I can't work with the gem in production mode. In local mode it works fine.
In the page, when i try to put a message in the chat, nothing happens.

I'm using nginx, passenger, thin.

Below it includes information that can be useful for support:

My private_pub.yml:

development:
server: "http://192.168.1.48:9292/faye"
secret_token: "secret"
test:
server: "http://192.168.1.48:9292/faye"
secret_token: "secret"
production:
server: "http://181.160.190.149/faye"
secret_token:"79301c39f07005f5e0ba58a4387c316c028d8c573fa3032b18c24d5ac35645935a64b93189eb19c514cfe34e0851a479b808041d32cd29735cfadd05f1a6f5c4"
signature_expiration: 3600 # one hour

In the nginx config I added a proxy:

location /faye {
proxy_pass http://127.0.0.1:9292;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_buffering off;
proxy_redirect off;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_set_header X-Forwarded-Proto https;
break;
}

Information about errors (when I try to put a message in the chat):

In the browser console:

Failed to load resource the server responded with a status of 500 (Internal Server Error).

In the file production.log:

hey man
Do you have solved your problem?
I using the this gem
on the local model worked fine
but on the vps server when I start the private_pub by rackup private_pub.rb -E production -s thin
the nginx report wrong (111: Connection refused) while connecting to upstream
but after stop the thin server ,it worked no problem
