C# Application using MIP SDK works on one machine but not on other ( fails at API profile_add_engine_async )

I have a C# Application built using MIP SDK to read / update sensitivity labels on a given document. This is a command line executable and it works just fine on one test server but not on another while both are configured as per the SDK documentation. All When compared the logs between a successful run on one DEV server v/s failed run on TST server, I see following difference at API - profile_add_engine_async

In both cases, I Token is printed on the console. So, till that point it is working fine.

Can someone help me understand why this happening and what I can do to fix it?

Success log :

    Resolved by Kalpesh Parmar by following the below steps:

    The root case was that the server where we had timeout issue did not have explicit WinHTTP Proxy setting. It had only Internet browsing proxy setting done via Internet Explorer -->LAN settings. After following the steps outlined in this article https://learn.microsoft.com/en-us/information-protection/develop/concept-mip-proxies and configuring the WinHTTP proxy explicitly using 'netsh winhttp import proxy source=ie' the issue got resolved.

    If you have any other questions or are still running into more issues, please let me know.

    Thank you again for your time and patience throughout this issue.
