Cannot access Jenkins Master URL on slave machine

Question

I'm trying to configure the Jenkins Master/Slave on our AWS windows server. I looked at other posts and researched online and followed the steps. I installed Jenkins on the server, and changed the jenkins url to the ip address of the server by command ipconfig: http://xxxx:8080/ . On the Jenkins xml file, I added the line to the argument: --httpListenAddress=0.0.0.0.

I followed the online tutorial step by step guide to set up master and agent. On the agent computer, when i try to access the url, it shows This site can't be reached. I added the port 8080 to the firewall. I also tried to ping from the agent to the master and it failed, said lost 4 100%. I am not sure how can I access jenkins master url outside of the server. Any help is appreciated.

The root cause is hidden in the comments, so for clarity posting it as an answer - looks like the problem was that the agent is running on a users laptop and it's trying to connect on a private IP of the jenkins server running in AWS. Things should hopefully work after connecting the agent on a public IP of the master instead.
