Hello, I’m new at Terraform and loving it… 
Except when I get stuck and can’t find answers. 
So I have a problem where my targets are coming up unhealthy. I see the talents and skills of many but for now I’m just trying to get a handle on the basics. Everything else works but the Target is coming up unhealthy in the target group. However, it’s showing quite healthy as an instance.
Thanks all.
