Cant bind multicast socket on Windows

[ashesman]

When using frontend_example.py on Windows 10, I am not sure why but an exception is thrown on line 108 of multicast.py when trying to bind to 239.1.1.1 on port 10000.

self._sock.bind((self.address, self.port))

The exception information is below:

(env) D:\openhtf> cd d:\openhtf && cmd /C "d:\openhtf\env\Scripts\python.exe c:\Users\Ashley.vscode\extensions\ms-python.python-2020.11.371526539\pythonFiles\lib\python\debugpy\launcher 60785 -- d:\openhtf\examples\frontend_example.py "
Exception in thread Thread-7:

@ashesman Thanks！

It looks like Google doesn't seem to care about this sort of thing. However, I still want to use the official library.
For that reason I'd recommend just changing the configuration.
My code is based on the frontend_example.py file:

...

def main():
    CONF.load(station_server_port='4444',
              station_discovery_address="")  # added this line
    with station_server.StationServer() as server:
        web_launcher.launch('http://localhost:4444')
...
