Trouble with activation

Hi, I am trying to activate  my Trados 2019 license on a new computer but I keep getting this error message: “Activation Failed Message - Could not connect to Activation server (403) Forbidden.” And when I try to do an offline activation, every time I enter my activation code the window disappears and it says: "The requested service is not available: Sdl.Desktop.Platform.Services.ITelemetryService." Can someone please help me?

Thank you
