ping

I wasn't able to ping to my ec2 server although I've done the following command:

ec2-authorize default -P icmp -t -1:-1 -s 0.0.0.0/0

when I try this again it gives me:

Client.InvalidPermission.Duplicate: The permission '0.0.0.0/0-3--1--1' has already been authorized on the specified group

now when I ping from my laptop it gives me:

PING 54.251.103.225 (54.251.103.225): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3

any idea on what to try on next?
