This is a link-local address, you have to specify the interface scope id:

fe80::1%em0
thanks for the hint. I fixed this but that alone still does not help me
to send IPv6 data.
Hetzner also needs to know your link-local address on em0,
do they use the fe80::921b:eff:fe8b:f34%em0 derived from the MAC (I think they
do)
or do you have to configure something like fe80::2%em0 on your side?
Thats a good question. Sadly they dont specify that in the docs and are
also not willing to answer that via there support staff.
All i could find in the documentation is the following line:
For IPv6 on dedicated servers and virtual servers from the CX line, the gateway
is fe80::1.
Since this is a link-local address, the explicit specification of the network
adapter (usually eth0) is necessary:
# ip route add default via fe80::1 dev eth0
There answer is that it works on Linux without config and OpenBSD is not
supported officially.
I just found out that since i changed my mygate up to your suggestion
that i now have to ping6 fe80::1%em0 first and then i am able to
connecto to other hosts via IPv6. But not before i pinged the
fe80::1%em0. WTF?
Here are my rountes before the first ping to fe80::1 and then after the
ping.
