Question

After Java App is deployed, I cannot access the ip address at all, be it on port 8080 or port 8443. Did I miss out any configuration setting

The WAR file was working earlier until we reset the server. Set up tomcat 8, jdk 1.8 and SQL.

Don’t you maybe have firewall enabled ? If you used ufw, you can check it’s status by running

  1. sudo ufw status

Firewall is off. I have done a netstat -a and it shows port 8443 is assigned to tcp6 which we have already disabled it on the droplet. Could this be a problem?
