OSError: [WinError 10022] An invalid argument was supplied

Might need to add in a platform check for Windows or Linux as the socket bind operation needs UAC for admin privileges.

I am using the SSDP library and wrapped the discover function with logic to check for windows and it triggers the UAC, however, I am still getting the OSError: [WinError 10022] An invalid argument was supplied

A similar issue was found on the SSDP library github

Using the tuple solution in the previous comment:

 connect = loop.create_datagram_endpoint(PrintSSDMessageProtocol, family=family, local_addr=(bind, 6666))
