Hi,

It looka like the Thread node have not been assigned a global IPv6 address from the border router. A global IPv6 address is required for accessing IPv6 devices online, otherwise you will only be able to access IPv4 devices through the NAT64 interface. The reason that your Thread node do not get a global IPv6 address is that your border router have a /64 prefix IPv6 address. The Thread specifications requires a /64 subnet for the Thread network, meaning that the border router needs a /62 or lower prefix in order to further divide the network into the Thread subnetwork. Please make sure you have a /62 or lower prefix from your ISP, and that your network infrastructure is able to provide your border ruter with correct prefix address. Have a look at this thread for more details.

Best regards,
Jørgen
