The ipv4 connection works

What is needed to get the ipv6 connection?

You really should be using the "actual" ip6 address and not the link address.

The router shows multiple ipv6 addresses for the device. How to distinguish which one is actual?

IPv6 Address 2600:1702:4860:9dd0:c210:8c59:6c38:52fd
