I’m trying to set up a RPi 3 as a web server using the public URL. I’ve set up the device with Balena Wifi Connect, and I’m not sure if this is causing an issue.
My docker-compose.yml file is:
version: "2.1" services: wifi-connect: build: ./wifi-connect-master network_mode: "host" labels: io.balena.features.dbus: '1' cap_add: - NET_ADMIN environment: DBUS_SYSTEM_BUS_ADDRESS: "unix:path=/host/run/dbus/system_bus_socket" Web_Server: build: ./Web_Server privileged: true expose: - "80"
I’m just getting an error saying:
We encountered an error when reaching this [balena.io](https://balena.io/) device: UUID 3ba5b6d5dc930ca665225936bfd3c62e `tunneling socket could not be established: 500` One possible reason is because nothing is listening on port 80 on the device.
I’ve granted support access and my UUID is 3ba5b6d5dc930ca665225936bfd3c62e
