How do I have my Nucleus+ diagnosed?

My home networked music system consists of:

  • a Home ethernet network with several switches.
  • a Nucleus+ core
  • over 100,000 songs stored on a Vortexbox ripper/server & a NAD M50.2 ripper/server streamer
  • a Devialet Expert Pro 220 integrated amplifier.
  • Dell XPS-8700 desktop computer using Windows 10 operating system.

I have a problem with Roon, either through my desktop computer or through my Apple i-phone 7 app, not being able to connect with my Nucleus+. I have tried numerous fixes suggested by the Roon community but none have worked. I have had several computer experts look at the situation and they are suggesting that there is something wrong with the Nucleus+. What steps should I now take to have my Nucleus+ server diagnosed?
