I'm setting up my first Amazon EC2. I already created the instance with Ubuntu using a tutorial on youtube. I configured the instance correctly, the Security Groups, the Elastic IPs, the SSH ports are on 22 and open to the world. Unfortunately, I still have the error Network error: connection timed out when connecting by Putty. This is also configured with the EC2 keypar. I have already followed several tips here from the forum and from Amazon itself but the error persists. Unfortunately as I am in the free plan of them I have no support to help me. Is there another factor that could cause this error?
To try to connect I am doing the following procedure.
I downloaded the key pair, I used puttygen to create ppk, I open the putty and I put the elastic ip address in Host, SSH access -> Auth and I find ppk and I'm going to open it. After a while he gives this error.
