Answer 1

Since, you said it works with the port 3000, but with port 3001 its not working, it should be most probably a security group issue, and you will need to change your security group definition attached to the EC2 machine, and add a new entry with

type - Custom TCP,

Port Range - 3001,and

Source - Anywhere-IPv4(or choose otherwise, if there is any restriction), and

Save rules.
