Unable to type in AWS Serial console

Question

I have access to the Serial Console for my EC2 instance, however once the after loading i am unable to enter commands in the screen. Not sure if the IAM user is missing any more access permissions. Currently below is the permission provided.

"Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ec2:GetSerialConsoleAccessStatus",
                "ec2:EnableSerialConsoleAccess",
                "ec2:DisableSerialConsoleAccess"
            ],
            "Resource": "*"
        },

{ 
           "Sid": "AllowinstanceBasedSerialConsoleAccess",                                       
           "Effect": "Allow", 
           "Action": [ 
                       "<*instance info>*" 
], 
          "Resource": "

Answer

Hello.

As far as I can see from the document below, there seems to be no problem with the IAM policy.

Why not try connecting to PowerShell via Systems Manager Session Manager instead of a serial console connection?  
You can connect by setting the policy "AmazonSSMManagedInstanceCore" in the EC2 IAM role.  
For EC2 in a private subnet, you need to set up a NAT Gateway or VPC endpoint.
