无法在 AWS Cloud 9 上创建环境

Cant create an environment on AWS Cloud 9

当我尝试在 AWS Cloud 9 上创建环境时,发生了这种情况:

The environment creation failed with the error: The development environment 'dda98b3b81134eb18121b0fdf83fdc66' failed to create. Delete the 'aws-cloud9-AlgumProjeto-dda98b3b81134eb18121b0fdf83fdc66' stack in AWS CloudFormation, and then try creating the development environment again..

我做账号的时候只能创建环境,关闭后重新打开另一个服务器,出现上面这个错误。

错误图片:

Cloud9 服务并非对每个地区都可用。请检查您正在为其创建环境的区域。尝试使用 US East (N. Virginia)us-east-1.
