If multicast is not working with Python on Windows but works fine on Mac, there could be several reasons for this issue. Here are a few troubleshooting steps to consider:

  1. Check network configuration: Ensure that multicast is enabled and properly configured on your Windows machine. Check your network adapter settings and confirm that multicast is allowed.

  2. Firewall and antivirus settings: Verify that your firewall and antivirus software on Windows are not blocking multicast traffic. Temporarily disable these security software or adjust their settings to allow multicast traffic.

  3. IP address binding: Check that your Python code is binding the socket to the correct IP address when using multicast. On Windows, it is recommended to bind to the default network interface IP address (0.0.0.0 or ::) rather than specifying a specific IP address.

  4. Administrative privileges: Ensure that you are running the Python script with administrative privileges or elevated permissions. Some network operations, including multicast, may require administrative access.

  5. Network driver or adapter issues: Update your network drivers to the latest version or try using a different network adapter if available. Outdated or incompatible network drivers can sometimes cause issues with multicast functionality.

  6. Test with different multicast addresses: Try using different multicast addresses (e.g., different IP ranges, multicast groups) in your Python code to rule out any conflicts with a specific address or group.

  7. Wireshark or network monitoring: Use network monitoring tools like Wireshark to capture and analyze the network traffic. This can help identify any issues with multicast packets not being sent or received correctly on Windows.

  8. Python version and libraries: Ensure that you are using the latest version of Python and relevant libraries for multicast communication. Update or reinstall the required libraries (e.g., socket, socketserver, asyncio) to ensure compatibility with your Python version on Windows.

By following these steps, you should be able to troubleshoot the multicast issue on Python running on Windows. It's also a good practice to refer to the documentation and resources specific to the libraries you are using for multicast communication in Python to find any additional troubleshooting steps or considerations.
