Setting up an Application Load Balancer to 2 Tomcats on EC2

Good morning, I have 2 Tomcats running on an EC2 (Windows Server 2022). They are serving requests on the Private IP of the EC2 via ports 8080 and 8081 and I can get to both the Healthy Target URL and App from the EC2 instance itself. I have 2 Target groups created. One accepts HTTP inbound and the other accepts HTTPS inbound. The Healthy Target check is sent to <EC2 Host><8080> and <8081> (index.jsp) via HTTP for both LBs The app resides at <EC2 Host><8080>/myapp/index and <8081> <EC2 Host><8081>/myapp/index

I try to create a Load Balancer (listening on port 80) and when I try to select a Target, the list is empty and refresh doesn't populate the list. What am I missing? Does the subnet of the target group have anything to do with it? please advise. thanks Charlie D
