Ok false alert,
I could'nt telnet my ip
telnet yourinstancepublicip 80
So I tried to look into firewalls etc, but it wouldn't solve my issue.
Then I realized that the Security Group was not "attached" to my instance.....
If someone has the same problem as me.
Go to instance, Acions > Networking > Change Security Groups
Then select your security group and Voilà!
