Have you tested with curl / wget from haproxy server if IIS/Exchange returns stautus=200 for /oab/healthcheck.htm ? curl -v -k https://ip.addr.e.ss/oab/healthcheck.htm and # this probably sends "correct" iis.exchange.domain.com SNI to iis server, # maybe iis/exchange needs SNI to serve correct file/status ? curl -v -k --resolve iis.exchange.domain.com:443:iis.ip.here https://iis.exchange.domain.com/oab/healthcheck.htm > Here are relevant haproxy logs showing the health check as good and > content still being proxied, even though the component is inactive (ie > health check page is not accessible) > Oct 29 14:51:39 <Server-Name> haproxy: [WARNING] 302/145139 (93952) : > Health check for server be_ex2019_oab/<SERVER_NAME_1> succeeded, reason: > Layer7 check passed, code: 200, info: "HTTP status check returned code > <3C>200<3E>", check duration: 8ms, status: 3/3 UP. > Looking at the IIS logs, when the component is active, I see the GET > requests from my workstations IP.

When you test /oab/healthcheck.htm with browser what url do you use: https://correct.domain.com/oab/healthcheck.htm or https://ip.addr.es.s/oab/healthcheck.htm ? Do you get different result with ip or hostname ? -Jarno -- Jarno Huuskonen
