How to solve this error. Please help us.

I set files about SSL On TsgcWebSocketServer.

function TfMAIN.RunWSServer( nPort: Integer): Boolean;
begin
Result := True;
if( sgcWebSocketServer.Active = False )then
begin
With sgcWebSocketServer.Bindings.Add do
begin
IP := '127.0.0.1';
Port := 80;
end;
With sgcWebSocketServer.Bindings.Add do
begin
IP := '127.0.0.1';
Port := 443;
end;

sgcWebSocketServer.Port := 80;
sgcWebSocketServer.SSL := true;
sgcWebSocketServer.SSLOptions.CertFile := 'C:\localhost.hpms.kro.kr\certificate.crt';
sgcWebSocketServer.SSLOptions.KeyFile := 'C:\localhost.hpms.kro.kr\private.key';
sgcWebSocketServer.SSLOptions.RootCertFile := 'C:\localhost.hpms.kro.kr\ca_bundle.crt';
sgcWebSocketServer.SSLOptions.Port := 443;

sgcWebSocketServer.Active := True;
end
else
begin
Assert( False, '** 이미 서버.실행중' );
Result := False;
end;
end;
