nginx change referer for proxy
Solution 1:
You say that the proxied server asks for a domain name as a referer. Try that domain name instead of IP address.
proxy_set_header Referer "http://proxied-domain-here.com";
Solution 2:
Few years later, but this could be helpful to somewhere, you miss the port at the referer header (:8080):
proxy_set_header Referer "http://192.168.10.10:8080";
I hope can be helpful.
