How to configure AWS Application Load Balancer to point to multiple ports on the same server

I cannot get access to the second port that I want to have to. So, here are the listeners I have in my ALB: enter image description here

Additionally, my TG-dev is not healthy: enter image description here

I am not sure what is the reason for this. Basically, what is my setup - I have Node.js API that is running on the AWS EC2 instance, on port 8080, and I run it using the PM2. However, configured a development purposes only API that is currently running on port 8081, again using the PM2. I have access to port 8080, but unable to access the server at port 8081. Here is my Security Group (SG) that is allowing the access only from the LB: enter image description here

This points to the initial SG that has rules for both ports: enter image description here

How can I achieve my goal to have access to both, 8080 and 8081, ports?

EDIT: Here is also my pm2 list and what actually is happening on port 8080 and 8081. Maybe the reason why I cannot access 8081 is that there is difference, but I am not sure how this is configured, cause we do not have contact with the person who designed this. Any ideas are appreciated! enter image description here

Your processes are listening on IPv6 only but your security group doesn't have ports 8081 and 8080 open for IPv6, only for IPv4.
