How to connect kafka to external server.ip

问题

I have Kafka set up on my local machine, and I'm using github.com/segmentio/kafka-go to implement consumer producer model and working fine with localhost. But wanted to connect to an external server that is running on EC2.

ip:= X_XXX_XXX_XXX

    func CreateTopic() {
        _, err := kafka.DialLeader(context.Background(), "tcp", "ip:9092", "indicator", 0)
        if err != nil {
    
            fmt.Println("error in creating topic: " + err.Error())
        }
    
    }
    
    func ListofTopics() {
        conn, err := kafka.Dial("tcp", "ip:9092")
        if err != nil {
            fmt.Println(err.Error())
        }
        defer conn.Close()
    
        partitions, err := conn.ReadPartitions()
        if err != nil {
            fmt.Println(err.Error())
        }
        
    
        m := map[string]struct{}{}
    
        for _, p := range partitions {
            m[p.Topic] = struct{}{}
        }
        for k := range m {
            fmt.Println(k)
        }
    }

when executing createTopic() function getting error like host not found or connection refussed and gone through some article to reslove this issue. but it was not usefull.

Made chanage to server.properties file like

advertised.listeners=PLAINTEXT://ec2-XX-XXX-XXX-XXX.us-east-2.compute.amazonaws.com:9092
listeners=PLAINTEXT://ec2-XX-XX-XXX-XXX.us-east-2.compute.amazonaws.com:9092

and modified like this too

In config/server.properties:

advertised.listeners=PLAINTEXT://X_X_X_X_X:9092

In config/producer.properties:

bootstrap.servers=X_X_X_X_X:9092

and added to sudo nano /etc/hosts

127.0.0.1 ec2-XX-XX-XX-XX.ap-east-1.compute.amazonaws.com

But still getting connection refused error and not host found if proerties file revered back.
