Amazon-ebs: Waiting for SSH to become available.SSH timeout

Hi, I am new to terraform and packer. I am trying to create a pre baked image but packer is failing while trying to to SSH to the instance. Its creating instance but then failing to SSH. I am using bastion host subnet which has access to IGW.

Hi! The good(?) news is that this is a super common sticking point, so don’t worry. It can probably get resolved. The bad news is that it’s nearly impossible to help people troubleshoot SSH connection issues without seeing their packer template and whatever preseed file you’re using to configure your instance. Mind sharing those using so we can talk in more specifics?
