00:00 create Ec2 Instance
02:48 Why browser SSH fails
05:37 One-click prefix list fix

8:05 Wrap-up

1️⃣ Launch your EC2 instance

Sign in to AWS Management Console

Open Services → EC2 → Instances → Launch instances

Name your instance (e.g. “MyFirstEC2”)

Choose an AMI (Amazon Linux 2, Ubuntu 20.04, etc.)

Key pair: create or select your .pem key → download & keep safe

Network & Security → Security group → allow SSH (port 22) from your IP (MyIP/32)

Click Launch instance

2️⃣ Why browser-based SSH fails

Terminal SSH uses your public IP → matches MyIP/32 rule

Browser SSH (Instance Connect / CloudShell) comes from AWS IPs → gets blocked by your strict rule

3️⃣ One-click fix with Managed Prefix List

In EC2 Console → Security Groups → select your SG → Edit inbound rules

Add rule:

Type: SSH

Port: 22

Source: choose “Prefix list”

Save

Now your console “Connect → SSH” always works—AWS keeps that list updated, so you never chase IPs again.
