[.NET] Could not create SSL/TLS secure channel

Zdravim komunitu. Mam takyto kod vo vb.net:

      Dim url As String = "https:\\example.com\folder\file.exe"

      Dim destination As String = "C:\path\to\save\downloaded_file.exe"

      Try

            ' Create the request

            Dim Arequest As WebRequest = WebRequest.Create(url)

            Arequest.Method = "GET"

            ' Get the response stream and write it to a file

            Using response As WebResponse = Arequest.GetResponse()

                Using Astream As Stream = response.GetResponseStream()

                    Using fileStream As New FileStream(destination, FileMode.Create, FileAccess.Write)

                        Astream.CopyTo(fileStream)

                    End Using

                End Using

            End Using

            Console.WriteLine("Download completed successfully.")

        Catch ex As Exception

            Console.WriteLine("Error downloading file: " & ex.Message)

        End Try

v ofise mi funguje bezchybne, na roznych systemoch (win 10 a win 11). na domacom pocitaci dostanem chybu: Could not create SSL/TLS secure channel. Obidva environmenty su rovnake: 64 bitovy system, Visual Studio 2019 Community ver. 16.11. Zaujimave je, ze z domaceho pocitaca mi WinSCP funguje bezchybne so SFTP. Ked zadam doma v browseri url na stiahnutie exe, tak mi to v pohode stiahne, aj vlastne vsetky operacie mimo VS2019 funguju korektne. Takze tam nebude nejaky blocker / filter podla IP, alebo tak nieco (na serveri). Doma mam slovensku IP adresu, v ofise rakusku. Skor ako zacnem otravovat vlastnika serveru, tak sa chcem opytat, ci niekoho nenapada, v com by mohol byt problem? Vychadza mi to tak, ze niekde v .NET, alebo VS2019, ale ozaj netusim kde. Dik za Vas cas.

Najskor ta binarka, ktoru skompilujes, nema povolenie pristupit na internet. Takze by som pozrel na nastavenia firewallu.
