use nginx for websockets with two different host/ports - nginx

Question

I have my play project running with non-ssl.So i decided to use nginx as front end proxy server for SSL. Now, i have two play project deployed. One is used to portal and one for rest application stuff.
Within my portal project (front end UI) , i have called websocket urls accessing the rest-api project for getting data.
The problem is i get security error when i use SSL for portal. I need to understand how can i pass the websockets . Here is my nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log debug;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
#include /etc/nginx/conf.d/*.conf;
server {
listen 443 ssl;
server_name 10.100.10.99;
ssl on;
ssl_certificate /etc/ssl/certs/punvm-core06.crt;
ssl_certificate_key /etc/ssl/private/punvm-core06.key;
ssl_session_timeout 5m;
ssl_protocols SSLv2 SSLv3 TLSv1;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://matrix09:9701; #portal url.
proxy_redirect off;
#WebSocket support (nginx 1.4)
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_read_timeout 86400;
}
}
}
The websocket are called from my javascript in my portal play project. From nginx understand i can give only one proxy pass .
So i have two sets of url .
1. http://matrix09:9700 - My rest url .
2. http://matrix09:9701 _ my portal url
In java script, i call websocket like this,
var WS_appstatus = window['MozWebSocket'] ? MozWebSocket : WebSocket
var appstate=new WS_appstatus("ws://matrix09:9700/services/reports/v1/realtimestreaming/smpApplicationStatus")
appstate.onmessage = function(event) {
var datapoint = jQuery.parseJSON(event.data )
app_status(datapoint);
}
PLease suggest.
