Description

HTTP3+QUIC

There is no $http_host value in http_v3, so there is no value when transmitting the Host Header to upstream.

`
listen 443 quic reuseport;
listen 443 ssl backlog=65000;
http2 on;
http3 on;
.....
proxy_set_header Host $http_host;
`

upstream $http_host Host http header nothing

Hello.
nginx/1.26.1, the problem is still relevant.
If we use HTTP3, then the $http_host variable becomes empty.
