caddy_reverse_proxy_upstreams_healthy missing in metrics page

[Sebclem]

Since update to 2.9.0, all the caddy_reverse_proxy_upstreams_healthy metrics are missing in the Prometheus metrics page.
All the others metrics are present, but those ones are missing.
I have checked the release note, and I don't see anything related to this. I have already moved metric out of servers
Here a part of my config :

{
  servers {
    trusted_proxies static 10.0.0.0/8
  }
  metrics {
    per_host
  }
  admin :2019
}


xxxxx.xxxxx.xxxx {
  tls /etc/ssl/acme/-.xxxxxx/fullchain.pem /etc/ssl/acme/-.xxxxxxx/key.pem
  reverse_proxy xxxxxx.xxxx:8096 {
    health_uri /health
    health_follow_redirects
    health_fails 3
    health_timeout 20s
  }
  log {
    output file /var/log/caddy/xxxxx.xxxxx.xxxx.log {
      roll_size 50mb
      roll_local_time
    }
  }
  handle_errors {
    root /srv
    rewrite * /{err.status_code}.html
    file_server
  }
}

Sorry. I missed wiring that up when I worked on metrics.
