AWS Launch Configuration error: The requested configuration is currently not supported

I have created a Launch Configuration with which I am creating a Auto Scaling Group.

When I create the Auto Scaling Group from the Launch Configuration, I get the below error:

Description:DescriptionLaunching a new EC2 instance. Status Reason: The requested configuration is currently not supported. Please check the documentation for supported configurations. Launching EC2 instance failed.

Cause:CauseAt 2017-08-15T10:54:52Z an instance was started in response to a difference between desired and actual capacity, increasing the capacity from 0 to 1.

I looked around and only found this link. However, it doesn't tell me what exactly isn't supported, so doesn't help much.

My Launch Configuration looks like this:

My Auto Scaling Group looks like this:

And:

Sorry I had to block some items out as it has the client's data.

Any input will help. As there is no information anywhere in the logs, I don't know where to go from here.

PS: I have tried changing the Instance Type but had no luck. Thought that might be the cause but apparently not.

Figured it out. My VPC was set to Dedicated Tenancy, which doesn't support all types of instances. The Dedicated setting was done in error actually. I deleted the VPC (you can't seem to change its Tenancy setting) and then created a new one, followed the steps for the Launch Configuration and the ASG created the instances without a problem.
