To access Jenkins running on port **** of your EC2 instance, you need to make sure that your EC2 security group allows inbound traffic on this port. Here’s how to do it:

1. Log in to your AWS Management Console and navigate to the EC2
   Dashboard.

2. Select your instance and go to the Security section.

3. Click on the Security Group associated with your instance.

4. Go to the Inbound Rules tab and click Edit inbound rules.

Add a rule:
Type: Custom TCP
Protocol: TCP
Port Range: ****
Source: Anywhere (or choose specific IPs for added security)
Save the changes.
