I cannot call my API from my C# application

What is the name of the domain?

What is the issue you’re encountering

I am making an API call to retrieve data and log in from a WinForms C# application, but I cannot connect to the API. But my website can log in normally, and I can also use Postman without any issues

What are the steps to reproduce the issue?

Simple: Use HttpClient (C#) to GET data from the website: https://25septembrestudio.com

It seems there is no issue with the API endpoint if you can successfully call it via Postman or cURL. Someone familiar with C# might be able to assist. What error do you see when calling the API from your application?
