How to use VVDI Prog to read BMW 5 Series ECU N55?

Question:

Xhorse VVDI Prog failed to read ECU N55 MEVD17.2.4 from a BMW 5 series 2014.  I am using the new Bosch ECU adapter. Is the server down or am I doing something wrong?

With Autohex or Yanhua Mini ACDP can do with adapter without boot pin (N55).
