SSL Configuration for HAProxy 1.6.12

Hi,
I need an assistance to configure the SSL properly in HAProxy 1.6.12, I am aiming to use HTTPS between browser and HAProxy, from HAProxy to backend, it will be HTTP. I loaded the public CA certificate from entrust successfully, I can see the application login page via https, howvere, when trying to login, its says “page cannot be displayed”, I am not sure if all the required configuration parameters related SSL are made in config file.

Appreciate you help on this? is there any detailed procedure to configure SSL in HAProxy.

global
maxconn 2000
chroot /etc/haproxy
tune.ssl.default-dh-param 2048
ssl-default-bind-ciphers ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256
