Well, yes, maybe I missed some info.

But hopefully someone figured it out, my ISP is using a link local
address that does not follow RFC 4129 which states that there must be 54
0 before the interface id.

https://www.rfc-editor.org/rfc/rfc4291.html#section-2.5.6

I asked my ISP to changeg the link local address, but no answer yet,
they are "working on it".
