Load balancer HTTPS monitor on Exchange 2016

[mike315]

Hello,

I have set up a load balancer for my Exchange servers, and it's working great, except for the HTTPS monitor :

HTTP monitor on Exchange : OK
HTTPS monitor on another server : OK
HTTPS monitor on Exchange : fail (LB marks it down)

The monitor is looking for a 200 code, which is provided here : /owa/healthcheck.htm
I also tried to monitor the IIS root folder directly, same thing.
My certificate is from a trusted CA.
And of course nothing in the LB logs...

Any help appreciated...

I highly doubt the built-in load balancer (relayd) is going to adequately handle a handoff with Exchange. You should install the haproxy package and use that instead.
