Ping is blocked by default. You should allow ping in security group.

1)1st find out which is security group

Click on instance name -> Security Groups (It will be default if u didn't configure any)

2) Go to Compute -> Access & security Select security group -> Manage rules 3) Click Add Rule

Rule - All ICMP Direction - Ingress

Then Click Add You will be able to ping to floating IP assigned to instance.
