Can't connect EBS volume to new EC2 instance

Question

EC2 instance (Ubuntu 20.04 LTS) and EBS volume are both in us-east-1a.
When attempting to attach EBS volume to the instance, I get this message: "The instance configuration for this AWS Marketplace product is not supported. Please see the AWS Marketplace site for more information about supported instance types, regions, and operating systems."
How do I fix this?

Answer

The instance created from Marketplace AMI which require instance state was stopped before attaching/detaching an EBS volume. You may try to stop instance first, then attach volume again. Please refer link below.

[Attach an Amazon EBS volume to an instance](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-attaching-volume.html)
```
If a volume has an AWS Marketplace product code:
* You can attach a volume only to a stopped instance.
