Disabling the firewall in Ubuntu on an Amazon EC2 instance

Question

How do I disable the Ubuntu server firewall running inside an amazon instance, though, without using ssh? I am not able to access via ssh because of the timeout error, I think it has a firewall on the server blocking but I can not disable it precisely because it can not access. I need to somehow disable it, directly from the Amazon web console. How do I do so?

I already configured the security group in several ways, so I finally left it, with all the ports open for testing.

My route table is:

My ACLs is:

My instance settings:

Already tried to connect like this using OpenSSH:

ssh -i "c: \ key \ owlcom.pem" ubuntu@ec2-54-149-193-61.us-west-2.compute.amazonaws.com

and so

ssh -i "C: \ key \ owlcom.pem" X.X.X.X <- elastic ip

and so

ssh -i "C: \ key \ owlcom.pem" ubuntu@x.x.x.x

none of them works on any of my computers using openssh or putty., setting the putty correctly with the key.ppk
