Connection ec2 instance operation timeout error using ssh

Question

After creating a new instance,I am trying to access my instance like below:

ssh -i private_key.pem root@my_instance_public_domain

but the operation is timing out,I have updated the private key file permission using

chmod 400

and also edited default security group by adding a new in bound rule,selecting SSH and source Ip as 1.12.34.0/32

but getting port 22: Operation timed out .

what I am missing.

Thanks in advance
