AWS EC2 - Putty Network Error : Connection timeout

When you try to connect to AWS EC2 instance some time we might hit "Network Error : Connection timeout"

We have to look into two place
One Security group of the EC2 instance >
Console > EC2 instance > Security groups > Check inbound and outbound open port

Which is not recommended to open 0.0.0.0/0



Then check the subnet assosiated VPC route table.
> VPC > Route Tables > associated Internet gateway  of the VPC.
