Jenkins not responding

I have newly installed Jenkins on my Amazon-AWS server. I changed the Jenkins port to 8081 and started it. I verified that the Jenkins is running on port 8081.

[ec2-user@ip-172-31-28-247 ~]$ ps -eaf | grep 8081
jenkins   1370     1  0 03:42 ?        00:00:11 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8081 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20
ec2-user  1611  1585  0 04:34 pts/1    00:00:00 grep --color=auto 8081
[ec2-user@ip-172-31-28-247 ~]$

However when I try to access the Jenkins using this url:
http://ec2-54-214-126-0.us-west-2.compute.amazonaws.com:8081

it says that

This site can’t be reached ec2-54-214-126-0.us-west-2.compute.amazonaws.com took too long to respond.

On the same server I am running tomcat on port: 8080 which I can access and it shows the tomcat homepage.

http://ec2-54-214-126-0.us-west-2.compute.amazonaws.com:8080/

I am new to Jenkins.

Check the guide "Set Up a Jenkins Build Server -- Quickly create a build server for continuous integration (CI) on AWS"

It does has a section about a security group for the Amazon EC2 instance, which acts as a firewall that controls the traffic allowed to reach one or more EC2 instances.

Maybe 8081 is not part of that security group.

Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
In the left-hand navigation bar, choose Security Groups.
Click Add Rule, and then choose Custom TCP Rule from the Type list.
Under Port Range enter 8081.
