Windows Server 2019/IIS: problem with HTTPS

Good morning everyone,
I installed a Windows Server 2019 on a Proliant Microserver to use it as a web server.

Everything works fine except one thing: after configuring the HTTPS binding on a website on which HTTP works fine, a client (whatever browser you use) is seen requesting access with authentication (thai is not enabled). While providing it (which obviously is not due, I am talking about a public accessible website) there is no way to access. In the server logs I find the following error:

"Received TLS 1.2 connection request from a remote client application, but the server does not support any of the cipher suites supported by the client application. TLS connection request failed."

Consider that IIS Crypto test says the configuration is correct.

Over the years I have installed several hundred websites on IIS (up to WS 2016) but with Windows Server 2019 it is the first and it is evident that I am doing something wrong or something is missing...

@AlessandroNasini-1470 You can try to run the Process Monitor tool to see what is trying to connect to it.
