I have a VPS which is running Windows server 2008 datacenter with one Static IP address.

I can access from Internet to my web services by specific port e.g mydomain.com:3000/api and mydomain.com:4000/api. I want to change this web services access address into sub domain method (child) like App1WS.mydomain.com/api and App2WS.mydomain.com/api

I add this line to host file

127.0.0.1      mobileapp.myrealdomain.com

Then in nginx, I add these lines at the end

 server {
        listen       80;
        #root html;
        root c:/apps/web;
        server_name  mobileapp.myrealdomain.com;
       location / {
           proxy_pass  "http://127.0.0.1:3000";
        }
}

Then I started my loopback project which is accessible via:

C:\apps\mobileapp>node .
Web server listening at: http://localhost:3000
Browse your REST API at http://localhost:3000/explorer

Then I've add Alias(CNMAE) record to DNS:

alias name: mobileapp
FQDN: mobileapp.myrealdomain.com
FQDN for target host: 127.0.0.1:3000.

From other location on Internet myrealdomain.com loads homepage but still mobileapp.myrealdomain.com showing 

server DNS address could not be found.

In VPS mobileapp.myrealdomain.com works properly and loads server up time

    DNS (mostly) doesn't handle ports, so if your api was reachable using `mydomain.com:3000/api`, remove the `CNAME` you added and use this one: `mobileapp.myrealdomain.com CNAME myrealdomain.com`. Nginx will do the proxying to the correct port. – Dusan Bajic Sep 23 '17 at 17:28
  • Dear @dusan-bajic I did but nothing is changed, I've add: `alias name: mobileapp FQDN: mobileapp.myrealdomain.com FQDN for target host: myrealdomain.com` I also made a child and add cname but still the same. – RSA Sep 23 '17 at 18:12

    If you go to https://toolbox.googleapps.com/apps/dig/ and test `A` records `mobileapp.myrealdomain.com` and `myrealdomain.com`, do they resolve to the same IP address? – Dusan Bajic Sep 23 '17 at 18:29
  • I add photo of A and CNAME to the main post. – RSA Sep 23 '17 at 18:52

    DNS propogation takes time. Please try `ping mobileapp.myrealdomain.com` from the machine where it doesn't work. When the ping shows you the ip then only you can test. DNS updates can take anywhere between 30mins to 2 days also depending on different conditions. So if you are in a hurry to test if the server works fine or not. Then on the machine you are testing make a host entry `51.XXX.104.172 mobileapp.myrealdomain.com` and then test. If it works then that means you are just waiting for DNS changes to propogate – Tarun Lalwani Sep 24 '17 at 06:18
  • Dear@TarunLalwani and @DusanBajic I don't know what was wrong yesterday. but the same rule with CNMAE that you already told me, today works fine. I tried several subdomains for other web services and they start right after DNS and nginx restarted. Thank you so much. – RSA Sep 24 '17 at 09:31
