SSH time out due to AWS Session Manager tunnel failure

_This issue was originally opened by @Venkat1505 as hashicorp/packer#10508. It was migrated here as a result of the [Packer plugin split](https://github.com/hashicorp/packer/issues/8610#issuecomment-770034737). The original body of the issue is below._

I am using the AWS Codebuild with packer for creating golden-ami. I am using the session_manager in packer to connect AWS.

I am getting the below error?

Can you please help?
