Pi Zero W and Pi 3A+ all connect to the cloud but all return "nothing is listening on port 80" errors on the public URL.

[GOTO-GOSUB]

I have tried to get the Balena-cam working today on both a Pi 3A+ and a Pi Zero W via the "Deploy with Balena" route but while both connect to my account / the cloud, each one yields the following error when trying to access the public IP address to view the camera:

"We encountered an error when reaching this balena.io device:
(ID)
tunneling socket could not be established: 500
One possible reason is because nothing is listening on port 80 on the device."

I have tried the current builds (as of today, 03/07/22) for the Pi Zero and both 32 and 64 bit versions for the Pi 3. In all cases I am using the official camera module and the hardware in each case works from Pi OS.

The other devices I have currently running other Balena tasks are all still connecting so I don't think it's a connectivity issue my end or a service issue at Balena.

Here is the log from the Pis on startup:

Can someone please offer me some assistance in this ?

Same here! I have tried this with "Deploy with Balena" and ended as you.
