Unable to connect to EC2 instance using Public IP address with ssh

Question

Hi.. i am new to AWS and learning.  
I've launched a new Amazon Linux 2 EC2 instance, but not able to connect to it using SSH with the public IP address allocated.  
Please note that I created a new VPC ( with new CIDR block - 10.77.0.0/16 ) and assigned here.  
  
Prior to this, when I created the same Amazon Linux 2 EC2 instance with default VPC, i was able to connect with ssh.  
Any help would be highly appreciated.  
  
Thank you,

Answer

Anytime.

Answer

1) did you confirm the security group has an inbound rule to allow port 22 from your ip address (Don't open it to all traffic!!!)  
2) Is the ec2 launched in a public subnet? A public subnet is defined as one that has an associated route table with an entry for 0.0.0.0/0 to an Internet Gateway (igw).  
  
It's either one of those two issues, or you have a firewall issue on the ec2..which is unlikely.

Answer

Thank you very much my friend.  
Looks like I needed to create a new internet gateway and add it to the route table that was missing.
