We have had one of our nodes (running on a NUC like device) up for some time with a public URL, but starting in the last day or two, this URL has stopped working. I tried rebooting but that did not help. I can access the local network IP address, and see that the server is up and running correctly.
Is this an issue on the back-end? Or is there a way to fix this on my side?
I get the following on the browser:
We encountered an error when reaching this balena.io device:
tunneling socket could not be established: socket hang up
One possible reason is because nothing is listening on port 80 on the device.
I am confirming the port 80 is still active
