Nginx proxy with websocket not returning data

[nk86]

I am trying to configure nginx proxy with websockets I am using jetty server
with cometd framework(sends connect request to server every minute). I am
able to do the websocket handshake and send my login request to the server
but I am not getting any response back. Can you let me know what is wrong
with my config file.

worker_processes  1;
events {
    worker_connections  1024;
}

http {
    include       mime.types;
    
    server {
        listen       80;
        server_name  test.abc.com;

location / {
proxy_pass http://110.90.22.202:8080;
proxy_redirect off;
#root /var/;


proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header X-Nginx-Proxy true;
}

error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }


}
