Internet-routable IPv6 not usable?

[ha-ves]

Describe the bug
Connection using Internet-routable IPv6 time out aborted?

At first, it would successfully be added to the list of PCs (unpaired ofc), but after a few seconds, it went "Status: offline" so I couldn't pair it but the test network resulted fine(?)

Steps to reproduce
Just put in any Internet-routable IPv6
