SSH Issues with instances launch in AZ US-EAST-1

Hello Oluwasegun,

Please check the following:

• Security group allows incoming traffic on port 22
• Network Access Control List (NACL) is allows traffic on port 22

More information can be found here: https://aws.amazon.com/premiumsupport/knowledge-center/ec2-linux-resolve-ssh-connection-errors/

Do also check If your EC2 instances are launched in the private or public subnets? If they are launched on the private subnets, you can use a bastion host to ssh.

To configure a bastion host, you can follow this link: https://aws.amazon.com/blogs/security/securely-connect-to-linux-instances-running-in-a-private-amazon-vpc/

Hope this helps!
