The following config is required in a `backend` section: backend example-backend balance roundrobin option httpchk GET /health_check server srv01 10.20.30.40:443 weight 1 maxconn 100 check ssl verify none server srv02 10.20.30.41:443 weight 1 maxconn 100 check ssl verify none The important parts are: 10.20.30.41:443 ssl verify none You can also specify verify all. As expected, this will verify all certificates, however this will generate extra load. For this example setup the `verify none` is good enough.
