Failed to create environments

Make sure the subnet the Cloud9 instance is deployed in is a public subnet. See: VPC settings for AWS Cloud9 Development Environments.

You can also use Systems Manager to access a Cloud9 instance in a private network. See: Accessing no-ingress EC2 instances with AWS Systems Manager

Hi! We're sorry you're facing an issue with Cloud9. Could you let us know which AWS region this occurred in and at what time (including timezone)?

Hi,

If that can help, try to create the environment from the cloudshell.

Open cloudshell (upright symbol [[>_]] in the aws console landing page (before notifications, support and region selection))

The shell takes about 1 minute to start, then execute that command:

aws cloud9 create-environment-ec2 --name c9-test-env --instance-type t3.small

You should have a response like this one :

{
    "environmentId": "15258..."
}

It works for me and it creates a cloud9 environment in the default vpc and a default public subnet (n.b. I tested in Ireland region with an admin user).

Then go to the cloud9 service page in the aws console and open your new created environment.

It takes also about 1 minute to start, and then you should be able to use cloud9 IDE.

If this works, try again in the the console (https://docs.aws.amazon.com/cloud9/latest/user-guide/tutorial-create-environment.html)

Hope this helps,
