nginx direct trafic to non domain name using IP and local names - nginx

Question

Using nginx on windows server I want to direct traffic into different ports using names that are non-domain names, first one works but second one never reach: why? what is wrong?
http://192.xxx.xxx.xxx/game: works
http://192.xxx.xxx.xxx/cms: never reach.
If I change names then cms works and game never reach.
server {
listen 80;
server_name game;
location /{
proxy_pass http://localhost:4040;
proxy_connect_timeout 60s;
proxy_read_timeout 5400s;
proxy_send_timeout 5400s;
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_redirect default;
}
location /uploads/ {
root c:\Ebrahimi\www\appGame;
}
}
server {
listen 80;
server_name cms;
location /{
proxy_pass http://localhost:2010;
proxy_connect_timeout 60s;
proxy_read_timeout 5400s;
proxy_send_timeout 5400s;
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_redirect default;
}
location /uploads/ {
root c:\Ebrahimi\www\appCms;
}
}
New code block as "Richard Smith" mentioned:
server {
listen 80;
location /{
proxy_pass http://localhost:4040;
proxy_connect_timeout 60s;
proxy_read_timeout 5400s;
proxy_send_timeout 5400s;
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_redirect default;
}
location /uploads/ {
root c:\Ebrahimi\www\appGame;
}
location /game {
proxy_pass http://localhost:4040;
}
location /cms{
proxy_pass http://localhost:2010;
}
}

The second server block can only be accessed using its server_name, for example: http://app.firouzeh-mfg.ir/
If you are accessing your server using its IP address, the request will be processed by the first server block (or the block marked as the default_server). See this document for details.
Your two URLs http://192.x.x.x/game and http://192.x.x.x/cms (assuming identical IP addresses) access the same server block and differ only by location.
For example:
server {
location /game {
proxy_pass http://localhost:4040;
}
location /cms{
proxy_pass http://localhost:2010;
}
}
