PermissionError: [Errno 13] error while attempting to bind on address ('0.0.0.0', 80): permission denied about airshare HOT 2 CLOSED

That was the ticket, thanks! Nothing visibly running on port 80, so I'll dive into what might be blocking it.

from airshare.

It defaultly uses the port 80, you might be running xamp/web server on the same port or disabled in firewall. Use --port 3400 or any other open port to use it until you figure out what's already running on port 80

Duplicate of #5. Ensure that nothing else is running on port 80, or try unblocking the port if it's blocked (check ufw if you're on Linux). Otherwise, you can use any other ports as suggested by @mohanpierce99.
