GLM,

 

Where are you running the curl command from. If you are not running it from the BASH shell on the LB it could be a firewall that is blocking the healthcheck probe.

 

If not it could be one of the below 2 things:

 

  1. There is some sort of auth system on your server which doesn't allow healthcheck traffic without host field. So you might want to check on the host field on the keepalive configured on your LB.
  2. It could also be a http version issue. In the healthcheck page the keepalive will be for http1.0 whereas the end point server only accepts http1.1
