unable to send messages because socket.io from the cdn is an old and flask doesn't support it ... i fixed it by changing where the cdn is fetched from to the latest version <script src="https://cdn.socket.io/3.1.1/socket.io.min.js"></script> in the base.html file

Hi. So when I'm running the code, i get this error. I directly took the code from this repo, so it shouldn't be with anything wrong with the code I have. I'm running on Visual Studio Code via Ubuntu 20.04, using python 3.8. Any help is appreciated!

Hey
I didn't watch the second part completely but when I run the main.py I receive this error :

Exception in thread Thread-1 (run_server):

    sock.bind(addr)
OSError: [WinError 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted

how do I fix it??

my py version: 3.10.1
my os: windows 10

please help me,
thanks
