[SOLVED] Not able to connect to Kafka on AWS EC2

Issue

I created an Ubuntu VM on AWS EC2 and in this same VM I'm running one instance of Zookeeper and one instance of Kafka. The Zookeeper and Kafka are running just fine, I was even able to create a topic, however, when I tried to connect from my local machine (macOS) from the terminal I get this message:

Producer clientId=console-producer] Connection to node -1 (ec2-x-x-x-x.ap-southeast-2.compute.amazonaws.com/x.x.x.x:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

Inside /config/server.properties I changed the properties listeners and advertised.listeners (see image below) as I read in many topics related to my issue, but still no way of being able to connect Kafka on EC2 from my local machine:

I really don't know what I'm missing here...

Kafka version: kafka_2.12-2.2.1

listeners=PLAINTEXT://PRIVATE_IP_ADDRESS:9092
advertised.listeners=PLAINTEXT://PUBLIC_IP_ADDRESS:9092

Solution

After almost 3 days of struggling I was able to find out the problem. In case someone also has the same issue, I solved it by configuring the Security Group on AWS and adding the port 9092 which is the port where Kafka is running by default.
