[HELP] SSL Certificates / Net 6 API :: Tutorial to set everything properly?

[Octopi]

I had been trying during weeks without finding a solution

That's my scenario

Server 1 : SQL Server :: Windows Server

Server 2 : Net 6 API :: PopOS LTS (Ubuntu 22.04)

 Microsoft.Data.SqlClient.SqlException (0x80131904): A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 31 - Encryption(ssl/tls) handshake failed)

Server 2 (API) needs SSL certificate to connect to Server 1 (SQL Server)

actual error

Client : Android Device that connects to Server 2 (API) trough Ionic App
I understand will also need SSL certificate

* I also tried Net 6 API on Windows Server, then I had problem when establishing the connection Ionic (Android App) to Windows Server :: yet Net 6 API connection with SQL was working flawlessly
