This is the ultimate AWS rite of passage! Spent hours once debugging unreachable instances only to realize ICMP needs its own invite to the party. Who's got a worse security group horror story? Spill it! #AWS #DevOps #CloudFails

I have two EC2 instances. EC2-A → client EC2-B (10.0.2.15)→ server running an app on port 8080 From EC2-A: curl http://10.0.2.15:8080 → works ✅ ping 10.0.2.15 → fails ❌ Security group is open for TCP 8080. Why does ping fail while curl works?
