How to intercept, analyze and log secure HTTP requests using .Net core Web API

I was facing a problem where a client app was making an HTTPS request to a server. The server was returning a 400 error.

Usually, these errors are associated with a bad request because the client is sending bad heathers or the body is malformed.

The problem was that the owners of the client app were saying that the application was correct and there was an error in the server.

The server owners were saying that the server was correct and the problem was in the client app.
