The above exception was the direct cause of the following exception:

I figured out a fix. add a tuple (hostname/ip_address, None) to the loop.create_datagram_endpoint() call. This binds the socket to the address which is what Windows needs.

Hi @gordonaspin,

there was an issue in the previous version with Windows. This issue should be fixed in version 1.2. You can use the new CLI to test it.

Cheers! Joe

The same for 1.3.0 in win10(22H2, 19045.4651) + Python 3.12.4 And add -b 192.168.xxx.xxx to bind to special ethernet and apply the workaround by gordonaspin works for me.

connect = loop.create_datagram_endpoint(PrintSSDMessageProtocol, family=family, local_addr=(bind, 0))

@yyjdelete I actually do have a Windows PC now. Do you have a code snipped I could use to reproduce and debug the issue?
