'Failed to authenticate HTTPS connection' while accessing ASP.NET Core 2.1 Web API from React Native

Question

I have an ASP.NET Core 2.1 Web API project that is serving data from an SQL Server database. I checked 'Configure for HTTPS' option while I was creating the API project in Visual Studio.

I need to access this API from a React Native project, and I have tried using the Fetch API for it. The method I am using works when I make REST requests to different APIs but it is not working for my own API project. When I make a simple GET request to the API, I receive a Network request failed error on my mobile device, while on the API end, following error stack is encountered:

dbug: HttpsConnectionAdapter[1]
      Failed to authenticate HTTPS connection.

However, the request works fine when I make it using Postman, and following is the result:
