  Just to rule things out. Have you've tried to access the NAV webservice on the android/php machine through a web browser or something? Do you get the WSDL page?
  
  If that is working I would expect that you have to fix the issue on the request side. The code that is making the request package that is send to the NAV app server.

  Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help http://xhr.spec.whatwg.org/
  soapjs.php:41:12
  Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://111.111.11.111:11111/NAV2018/WS/SystemService. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

  The Same Origin Policy disallows reading the remote resource

  To me this looks like that the request is blocked from the site you're developing that launches the request to the NAV webserver. I think your webserver is configured to only access sources from localhost and not from remote servers (your Dynamics NAV server).
  
  More information about Access-Control-Allow-Origin. You can configure the webserver to allow resources from another origin/server. You can also test if this is the issue by including this into the header from your PHP script.
  
  Anyway I doubt this is a Dynamics NAV Webservice issue. You might as well try other forums

  The only enpoint in NAV which allows CORS requests are the new api page:

  Hi Sam, I had the exact same issue with Ionic/Javascript AJAX soap call. It looks like a direct connection to the exposed codeunit isn't supported as you can't set the CORs header/method in the NST config. I went back to the proxy method, made a C# ASMX web service that wraps the NAV gateway function. I let the ASMX handle the authentication.
  
  Also in IIS for the proxy I set the CORs properties (Origin/Method etc.). This isn't a great solution as I'd ideally wanted to rule out using a proxy due to non on premise customers (D365 BC) but what can you do?
  
  Anyway give me a shout if you want the code snippets, happy to share the Ajax / ASMX if it helps.
  
  Cheers Andy, Dionix
