Load Balancer - Health Check - Question about the LOADBALANCER_HEALTHCHECK_HOST Setting

Hello,

I’ve been playing around with the Load Balancer (Pro) feature and have a question about how the Health Probe can target a custom Health Status Page hosted on its own dedicated site (aka, a site that only hosts the health probe page). The Health Status Site still being hosted on each of the backend nodes.

When setting the Health Status Site’s binding to *:443, Bunkerweb is able to successfully get a response from the page. However, I’m hoping not to have the Health Status page being the catch all site. Setting a host header value on the site and defining it in the Load Balancer using the LOADBALANCER_HEALTHCHECK_HOST setting returns a 403 from the backend servers when the Health Probes tries to request a status.

I’ve captured a pcap of the HTTP Health Probe traffic and I do not see any host header value within the HTTP Stream, and I wonder if I’ve misunderstood the purpose of the LOADBALANCER_HEALTHCHECK_HOST setting or if I’ve configured it incorrectly.

Regards,
