But by ss -nat, IPV4 443 is not listend. How can I fix?
# ss -nat | grep LISTEN | grep 443

By default, Linux processes that listen on an IPv6 port will also listen
on the IPv4 port (when no specific address is specified):
http://man7.org/linux/man-pages/man7/ipv6.7.html
You could change that behavior by modifying
/proc/sys/net/ipv6/bindv6only, but your system is working normally now.
