Hi,
I made this check earlier, with wired and wireless and what I found that only when I have wired connection, Balena host start to LISTEN on port 80. I see this from Balena host CLI not Pi Hole console, so not sure who is responsible for this behavior.
Wireless only:

Active Internet connections (servers and established)

Wired :
