Tunneling socket could not be established: socket hang up

[sarzali]

Hi

I am new to resin.io, I create an application, download img, flush on card and insert into rasberrypi. It showing devices it connected but can not installed any git.
OR
I can not connect via
We encountered an error when reaching this resin.io device:

UUID 4609d4113a8f89ac43a9ef04c8d4f975

tunneling socket could not be established: socket hang up

One possible reason is because nothing is listening on port 80 on the device.

Hi @sarzali
If you do not have an application deployed to the device or the application running in your container is not listening on port 80 then you will see this error when trying to load the public device URL. Try pushing a sample app such as our simple node server project.
