How to open port 3000 on AWS

Question

I have seen many questions related or same as mine but I am not able to get the right answer.

I am developing the node js application and hosted on AWS. But I am not able to open the port 3000.

I am checking if the port is open or not using the following command:

 netstat -ntlp | grep LISTEN

Security group:

In bound:

Out bound:

Answer 1

Assuming NACL , Security Group and IP Tables are configured correctly.

I had faced similar problem with Node Once and Double Checked every setting , at last I found out A node service has to be attached to that port in order for it to work.

Even if the port is open it will not show open when you ping unless you have service attached to it.

You Can try something like http.createServer(app).listen(3000)

Hope it Helps!
