AngularJs Client side not connecting to server side - angularjs

Question

The problem is client side is not able to connect to server side. The issue as for as I know it is sending Request Method OPTIONS instead of GET. Look at these headers
General:
Remote Address:127.0.0.1:9000
Request URL:http://localhost:9000/api/v1/gyms
Request Method:OPTIONS
Status Code:404 Not Found
Response Headers:
view source
Content-Length:26454
Content-Type:text/html; charset=utf-8
Request Headers:
view source
Accept:*/*
Accept-Encoding:gzip, deflate, sdch
Accept-Language:en-US,en;q=0.8
Access-Control-Request-Headers:accept, accept-language, authorization, dev
Access-Control-Request-Method:GET
Connection:keep-alive
Host:localhost:9000
Origin:http://localhost
Referer:http://localhost/VTraining
User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.71 Safari/537.36

Isn't the General header should have GET Request Method. I deployed the client application on nginx.
This is my nginx.conf file HTTP settings.
http {

add_header Cache-Control "public";
}
location / {
try_files $uri /index.html;
if ($request_method = OPTIONS ) {
add_header Content-Length 0;
add_header Content-Type text/plain;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers 'origin, x-requested-with, content-type, accept';
add_header Access-Control-Allow-Methods 'GET, POST';
return 200;
}
}
}
