Problem with updating / installing plugins (latest HB)
Hey, 
I have a problem, after installing HB on Pi, I can't install / update plugins 
and after installing "Homebridge Config UI X" it has an update. 
I get an error:
```
npm ERR! code EAI_AGAIN
above sea level ERR! errno EAI_AGAIN
above sea level ERR! request to https://registry.npmjs.org/homebridge-sonos failed, reason: getaddrinfo EA
```

I admit that it works on Windows 10, but not on Raspberry Pi 3.
