Trouble getting Public URL to work

I’m following a guide- Build a Raspberry Pi-based network camera using WebRTC ref: “
but having trouble getting the public url to work. Below is the error detail:

We encountered an error when reaching this device:

UUID 56xxxxxxx

tunneling socket could not be established: 500

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

Any help would be appreciated.

Hello Sahil, as a few first troubleshooting steps, definitely be sure to set the “gpu_mem” variable, many folks miss that.

But beyond that, are all of the containers downloaded and running? Are there any errors in the Logs? And, of course, definitely try rebooting the device, just to be safe.

Additionally, what kind of a Raspberry Pi is it? What kind of a camera? Does the camera work in Raspbian?


Hello David Tischler,

Thanks for your help and troubleshooting guide. Yes, I noticed container application was not running properly.

Hi there,
just to clarify, were you able to solve the problem? Was it related to an application problem?
