Cannot connect to SQLServer in os authentication mode

Cannot connect to SQLServer in os authentication mode

Hello!

Delphi 11.3 Pro.
This is my connection configuration:
object UniConnection1: TUniConnection
    ProviderName = 'SQL Server'
    Port = 1433
    SpecificOptions.Strings = (
      'SQL Server.Authentication=auWindows')
    Server = 'DESKTOP-4J9A9E5'
    LoginPrompt = False
    Left = 160
    Top = 216
  end
SQL server engine version 15.0.2101.7
Result: 
---------------------------
Error
---------------------------
TCP Provider: No connection could be made because the target machine actively refused it.
.
---------------------------
OK   
---------------------------

However, i can connect fine from Management Studio 2018 with the same sort of configuration.

I have added a SQLServerUniProvider1 to the form. 

Suggestions?

Thanks!!
