Established connection to using port 443

Volumio version 2.861 released 22 Dec 2020, and Raspberry Pi 2 Model B Rev 1.1.

Why does the netstat program show a process named “node” sending TCP traffic to IP address on port 443 (https)?

Now this unknown IP address is blocked by means of firewall settings. It was done at my Raspberry Pi using iptables, and at my router using rule definitions.

I will also block any other unknown IP addresses that show up while running Volumio.
