NGINX not passing header to proxy

This problem was resolved with the help of the cloud provider. Turns out I
need to set the Host header
proxy_set_header Host upstreamhostname;
It wasn't exactly clear any any docs (on their end) this was necessary but
glad it's solved and makes some sense as well I suppose.
Thanks for all your suggestions Francis.
