Do you have `ProxyPreserveHost on` configured? I assume not.

If you set `LogLevel proxy_http2:trace2` we can observer what authority is
constructed from what input. The error.log then contains lines

authority=%s from uri.hostname=%s and uri.port=%d

The only way I could see the code not adding the port is when ipv6 addresses
are involved. Is that used in your setup?
