# Amazon ECS API failure reasons
<a name="api_failures_messages"></a>

When an API action that you have triggered through the Amazon ECS API, console, or the AWS CLI exits with a `failures` error message, the following might assist in troubleshooting the cause. The failure returns a reason and the Amazon Resource Name (ARN) of the resource associated with the failure.

Many resources are Region-specific, so when using the console ensure that you set the correct Region for your resources. When using the AWS CLI, make sure that your AWS CLI commands are being sent to the correct Region with the `--region region` parameter.

For more information about the structure of the `Failure` data type, see [Failure](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_Failure.html) in the *Amazon Elastic Container Service API Reference*.

The following are examples of failure messages that you might receive when running API commands.

**Note**  
Besides the failure scenarios described here, API operations can also fail due to exceptions, resulting in error responses. For a list of such exceptions, see [Common Errors](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/CommonErrors.html).
