Not sure if I should be concerned or not, or for that matter if this is the correct location to post this.
For time to time, my IPS/IDS picks up that my Volumio instance is polling an external IP address across lots of different ports. The source is my internal IP but the target is: 220.127.116.11:80
A "Whois" identifies Digital Ocean - this is a known hosting service, and good one at that.
But I wonder if anyone can suggest/advise if this could be a problem or is just an occurrence where the Volumio instance has lost connection with it's "mother-ship" service controller and trying to "phone home" using different ports?
