Weird ping timeout on AWS EC2 instance

I have an weird issue with EC2 instance:

  • I start a new Ubuntu instance (or any other).
  • It initialize the instance and I can ping and connect via SSH, fine...
  • Suddenly, I can't ping anymore! :(

I have enabled all TCP, UDP and ICMP (inbound and outbound) connections in the instance's Security Group. But no luck.

I also have tried connecting via SSH using Putty. No luck too.

I have searched a lot, but everyone says about the Security Group, which I already had configured to allow all traffic.

Any help will be appreciated! Thanks!
