That's not a "Refresh" header field.

That is something in the http response body.

In general, nginx doesn't mess with the response body.

(You can configure it to, but I tend to dislike doing that.)

Why does your back-end include the string "http://192.168.1.9/" in its
response body?

Can you make it instead include a string based on the Host: header it
receives? If so, that is what the "proxy_set_header Host $host" is for.
