The "create new ec2 instance" wizard is not allowing me to select existing Security Groups

Question

I have a carefully crafted and secure Default Security Group that should be used for this new ec2 instance. However none of my existing SG's are included in the Configure Security Group screen. Instead two new ones are shown that are worse than useless

Port 80 open to the world ??

Why are my existing security group's not displayed? Note I have checked the Region is the correct one containing the properly constructed SG's.

Answer 1

Based on the comments.

Security groups (SGs) are VPC specific. Thus, the issue was caused by launching an instance in a different VPC then intended. Subsequently, expected SGs were not available for the instance.

The solution was to use correct VPC.
