What value do you think $sent_http_x_host has, and why do you think that?

Compare $http_name and $sent_http_name in
http://nginx.org/en/docs/http/ngx_http_core_module.html#variables
with $upstream_http_... in
http://nginx.org/en/docs/http/ngx_http_upstream_module.html#variables

and then use $upstream_http_x_host.
