Solution

Console

1 . Go to EC2 service - > Click on "Security Groups" under "Network & Security" You should see at least one security group. One of them is called "default"

2 . Click on the security group with HTTP rules and click on "Edit inbound rules". Remove the HTTP-related rules and click on "Save rules"

3 . No. There is a time-out because we removed the rule allowing HTTP traffic.

4 . Click on the security group -> edit inbound rules and add the following rule:

  • Type: HTTP
  • Port range: 80
  • Source: Anywhere -> 0.0.0.0/0
