Issue with HTTP health monitors

I would make sure the server is responding to the health check, try to telnet to the server using the port the server listens on. Example > the server is an HTTP server,

 

then from DOS prompt an easy way to check a server is with telnet but specify the tcp port 80 if its an http server.

 

telnet 10.x.x.x 80 if the server http service is working it will connect and display a blank window if the http service is not up it will time out and window won't open

 

or use curl from cli, the command below would check the server at 10.99.44.99 using a host header of healthcheck.google.com and asking the server for the page at /health/heartbeat.html

 

to test a probe

 

curl -v -k -G --header "host:healthcheck.google.com" http://10.99.44.99/health/heartbeat.html

 

if ts working you should get a 200 http response in the output.
