[users@httpd] Health Check is not working, always shows a node up.

[Vladimir L]

I am testing with 3backend nodes, 1st returns 404, the third is not
responding at all, but Apache seems never tries to send a health check
there. All nodes are shown Init OK in Balancer Manager all the time. Apache
2.4.23 RHEL
