I have a problem for a few days with EVERY EC2 INSTANCE that I create. I set up the group security, the jira installation file, the database. Then I open the installation URL and a DB test connection is working but when I submit, it take a few minutes loading then the whole server is down and the installation is aborted.
BTW : I'm new in AWS so I only changed and added ports in the security group.
Some Screenshots :
