Not able to Run on EC2 instance

I’m trying to run daphne on stand alone EC2 instance (without EB), but when I fire daphne -b localhost -p 8001 project.asgi:channel_layer, I’m not getting anything back from console. On my local system (Ubuntu 14.04) it works fine but with the same configuration on EC2 it does not show any response after firing command. I also checked Log file of Daphne but its empty altogether.

PYTHONUNBUFFERED variable is forcing python to print output char by char as soon as it’s available. Instead of holding some buffer before flushing stdout.

But I have a better suggestion in mind. We should use hunter tracing tool for looking what’s going on under the hood.

Install it into your AWS instance into the virtual environment with Daphne.

pip install hunter

Run Daphne with tracing enabled.

PYTHONHUNTER="Q(module__regex='daphne.*') | Q(module__regex='asgi.*'), threading_support=True, actions=[CallPrinter]" daphne <your-channel-layer>

Please, attach hunter output to the pastebin-like service because output will be really huge. But it will help to understand what’s going on.
