Hi there,

you've found something that works for you, so you can stay with that

I find that it is usually worth understanding *why* configurations fail,
so it might be worth investigating happened there.

They can be useful if the proxied server is configured to care about them.

Perhaps nixneo.com responds differently based on the source address; but
from where I am, it looks like you have a redirector, not a reverse proxy.

When I access the IP address of nixneo.com, if I make a http request
with anything other than a Host: header of "nixneo.com", I get a 302
redirect to http://nixneo.com/

So to get useful content back in a proxy_pass location, I'd need to set
the correct Host header.

All the best,
