Hi,

1. I have created a new environment (tomcat) with Elastic Beanstalk and uploaded my war application.
2. Application works fine with http (80)
3. inbound port https 443 entry created into respective security group.
4. New Load Balancer created.
5. Listener 1 http redirect to https 443
6. Listener 2 https forward to a target group (ssl selected)
7. Target group created with port 443 directed towards the respective instance.
8. After some time, Target group always shows health status as unhealthy.

Kindly suggest.
