I have been working through the instructions on this blog here to make a radio reciever.
I have installed the balenas on a raspberry pi 3, logged in via balena CLI and pushed the project (which I downloaded direct from github GitHub - balenalabs-incubator/sdr-spectrum-monitor: Running OpenWebRX on balena to monitor radio spectrum and stream audio.)
I saw the blue ascii unicorn at the end so presumably that went ok.
Back in the dash-board on the balena cloud website I can click in to my raspberry pi and get it’s local ip address but when I try to go to it via a browser with port 8073 I get an error that the site refused to connect.
I have tried enabling a public URL and making a device variable “ORX_WEB_PORT” for port 80 but then I get this error:
We encountered an error when reaching this balena.io device:
tunneling socket could not be established: 500
One possible reason is because nothing is listening on port 80 on the device.
To be honest I’m not really sure what I am doing as this is the first time I’ve used Balena.
To check it wasn’t something to do with my network I setup a simple webserver on another computer and checked I could load a web page from a variety of ports including 8073 and that much worked so it must be something I did wrong in Balena.
