Windows Cygwin rsync version 3.4.1，add address = :: Unable to start the process

[fkxq4me50kksl]

error: rsyncd: PID 3776: rsync: getaddrinfo: bind address ::: Name or service not known
May I ask if anyone has encountered this situation?

By default, only IPv4 listening is enabled. I want to enable both IPv4 and IPv6 listening simultaneously.
