when use IPv6 on windows 10 in network adapter settings. I don’t know if this issue is only on my machine, or is for other user.
Please make sure your network provider supplies full end-to-end IPv6 connections and does not block certain addresses. Ping won’t reveal much as it is disabled for security reasons.
Also, again, make sure the network settings have been configured correctly in Control Panel.
We do support IPv6. Give it a try: http://www.ipv6proxy.net/index.php
