Trouble Establishing Connection to EC2 Instance Created with AWS CDK

[mohilmakwana31]

I am struggling with an issue in AWS CDK. I tried to create an EC2 instance with AWS CDK, and an EC2 instance was created with the given configuration. I allowed inbound traffic from all over the internet. However, after creation, I cannot connect to the instance from the AWS console.
For reference, I attached code below :

from aws_cdk import (
    Stack,
    aws_ec2 as ec2,
    CfnOutput,
    CfnTag,
    aws_iam as iam
)
from aws_cdk import aws_route53 as route53
from aws_cdk import aws_route53_targets as targets

from constructs import Construct

class CdkTrsting1Stack(Stack):

    def __init__(self, scope: Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        # VPC
        vpc = ec2.Vpc.from_vpc_attributes(
            self, "VPC",
            vpc_id="vpc-",
            availability_zones=['us-east-1a'],
            public_subnet_ids=['subnet-'] # Specify the actual subnet IDs here
        )

        # Security Group with inbound rule from everywhere
        security_group = ec2.SecurityGroup(
            self, "SecurityGroup",
            vpc=vpc,
            allow_all_outbound=True,
            security_group_name="AllowAllInbound",
        )
        security_group.add_ingress_rule(
            ec2.Peer.any_ipv4(),
            ec2.Port.all_traffic()
        )

        # IAM Role
        role = iam.Role(
            self, "EC2FullAccessRole",
            assumed_by=iam.ServicePrincipal("ec2.amazonaws.com"),
        )

        # Attach policy with full EC2 access to the role
        policy = iam.PolicyStatement(
            actions=["ec2:*"],
            resources=["*"]
        )
        role.add_to_policy(policy)

        # Create EC2 instance
        instance = ec2.Instance(
            self,
            "MyInstance",
            instance_type=ec2.InstanceType("t2.micro"),
            machine_image=ec2.MachineImage.generic_linux({
                "us-east-1": "ami-07d9b9ddc6cd8dd30"
            }),
            vpc=vpc,
            security_group=security_group,
            associate_public_ip_address=True,
            key_name="llm_startup_test",
            role=role
        )
        
        publicIp = instance.instance_public_ip;

        # Define Route53 hosted zone
        zone = route53.HostedZone.from_hosted_zone_attributes(
            self, "ExistingHostedZone",
            hosted_zone_id="<zone-id>",
            zone_name="<zone-name>"
        )
        
        # Create Route53 record
        record = route53.ARecord(
            self,
            "Route53",
            zone=zone,
            record_name="trial",
            target=route53.RecordTarget.from_ip_addresses(publicIp),
        )

        # Output Instance ID
        CfnOutput(self, "InstanceId", value=instance.instance_id)

Probably you would need to create EC2 instance IAM profile to access ec2 via EC2 Instance Connect
