The response is a 200 OK, so if that URL is served by a proxy, then the response is generated
from your origin. That’d most likely imply it’s not a remap.config problem. Just looking
at the response, a wild guess would be that you might need to turn on pristine host headers
before forwarding to your origin. In records.config, change

	CONFIG proxy.config.url_remap.pristine_host_hdr INT 1

So, assuming you had a remap.config rule like

	map <> <>

With the default config (pristine off), the origin server would see

	Host: <>

With the config change above (pristine on), the origin server would see

	Host: <>

I prefer keeping pristine host headers at the default (OFF) when possible. That means you
will need to change your origin server to accepts the remapped host header, but I always find
this to be a more reliable approach with explicit configurations and expectations.

I hope that helps?
