Hi,

I have created a Launch configuration using the below cloud formation template and created Autoscaling group using AWS Console. I am getting the below error while launching Ec2 instance using Auto scaling group.Please find the screen shots.

Error:

Launching a new EC2 instance. Status Reason: The parameter groupName cannot be used with the parameter subnet. Launching EC2 instance failed.

Cause:CauseAt 2020-04-29T07:46:29Z an instance was started in response to a difference between desired and actual capacity, increasing the capacity from 0 to 1.
