okay so thanks to a friend who helped me figuring out what was going on
here is the answer :

basically the application was running on a Windows Server 2012 instance and
the windows firewall was preventing any traffic towards my application.
Adding the application to the allowed applications list for the windows
firewall did the trick.

so here is a recap on what to do to make it work

my server app is now bind to tcp://*:5556    and my client connects to

via the EC2 console management , add the security group rule

Custom TCP  Aywhere on port 5556
on the server make sure you add the server executable to the allowed
applications list.

hope that helps others who might have the same problem :)
