Node 2i Excessive DNS Requests to AWS

Answered

I have a Node 2i that is sending massive numbers of DNS requests to Amazon Web Services.

 

The issue began a few days ago, but I don't recall whether there was an update around this time or not.  I do not have the Amazon music service configured.

 

I have a Node N130 that does not exhibit the same behaviour - no excessive requests.

 

Anyone have any insight?

 

Here are a few screenshots from my pi-hole dashboard.  I took these pics a few days ago - in the last 24h, the DNS request count has increased massively - more than 149000 requests!

  I also have a Node 2i doing the same thing - it's making constant DNS queries to Amazon AWS - a quarte of a MILLION in one day! Please advise

  Bluesound support advised the following:
  
  "Along with this, we've seen from your diagnostic log for your player that it is standing on a signal strength of -66 dBm.
   
  Bluesound players will start noticing hiccups and unexpected issues at around -60 dBm, and users of the EU wireless spectrum can even expect to add about -5 dBm to their estimation."

  I had a spare port on an ethernet switch in the same room as the Node2i... after hard wiring the Node2i to the switch, the excessive DNS queries stopped.  In my case, the Node2i was in the same position for more than 18 months with no previous issues - no excessive traffic and no playback or streaming issues, until one day, there were. 

  They also suggested the following:

  "The issue you are seeing is not firmware related - it may however be caused by an error with the network device table of your router. A network power reset should resolve this.
   
  A router reset tends to clear the DNS request codes you receive."

  In my case, all of the DNS queries were being answered successfully (as depicted in the original screenshots above) - it didn't seem to me that it could be a routing issue as every request from the Node2i was answered, yet the device kept requesting. 

  Anyway, hard wiring it resolved my problem.  I'd prefer to remain on wifi, but this is fine for now.
