Tomcat无法从EC2实例访问（Ubuntu 14）

Question

I am not able to access the tomcat using public IP of EC2 Instance. I can access it using http://localhost:8080 internally but not from outside. In fact, It was running good since 2 months but suddenly it stopped and now I am hanging in between. locally my application is running fine and I can ping to my Instance using Public IP. Security group defines access to all traffic (TCP,HTTP,SSH). Then why Tomcat/Application is not being accessed externally. Any help will be highly appreciated. Thanks

Answer 1

You have to define security group rule.

Security Groups -> Inbound -> Edit:

Custom TCP Rule : TCP: 8080 : Source Anywhere
