I use project : " WiFi-enable USB printers with a Raspberry Pi and share it over your network", and I have a problem:
We encountered an error when reaching this balena.io device:
UUID 295bbe7c90df1f7f73fb2ade415fa06b
tunneling socket could not be established: 500
One possible reason is because nothing is listening on port 80 on the device.
Hi there,
When you look at the device in the balenaCloud dashboard, have you got the cups
service and is it running? Is there any logging from that service shown?
