By default, Jenkins will not be accessible to the external world due to the inbound traffic restriction by AWS. Open port 8080 in the inbound traffic rules as show below.

EC2 > Click on your Instance
In the bottom tabs -> Click on Security
Click on link below, Security groups -> Edit Inbound rules
Add inbound traffic rules, you can just allow TCP 8080 as well, I have allowed All Traffic

Login to Jenkins using the below URL:
