Actual behavior

When attempting to launch the debug server, I receive the following error:
There was an error in starting the debug server. Error = {"code":"EACCES","errno":"EACCES","syscall":"listen","address":"::"}
I'm behind restrictive corporate Firewall, which I suspect limits the ability to launch the debug server.
I am generally unable to run any servers that binds to 0.0.0.0, but I am able to bind explicitly to 127.0.0.1 without any issue (tested with NodeJS).

Can I somehow configure which IP address (and port) the Python debugger attempts to bind to?
