Sorry, but I'm back :(.
I've been googling this all night yesterday and all day today, but
all i can see is that a lot of people are having the same problem
and that there's bugs in Neutron. However, they're all quite old
and this is Mitaka, so it should be fixed.. ?
Many refer to a "metadata_proxy.ini" file or something like that.
A file i don't have. But on the other hand, the settings they use
in there is available in my neutron.conf so..
The curl client in the instance gives me:

I'm not sure if this is still a bug, or if i just missed some
configuration. But I've checked and double checked (and tried
varios examples) and they look ok. Let me know what kind of info
you need, and I'll provide.
