AWS SNS EndpointDisabled

The endpoint is disabled and cannot receive messages.

Resolving the 'EndpointDisabled' Issue in AWS SNS

Understanding AWS SNS

Amazon Simple Notification Service (SNS) is a fully managed push messaging service that allows you to send notifications from the cloud to endpoints such as mobile devices, email addresses, and HTTP endpoints. It is widely used for sending alerts, updates, and notifications to subscribers.

Identifying the Symptom

When using AWS SNS, you might encounter the 'EndpointDisabled' error. This error indicates that a specific endpoint is disabled and cannot receive messages. As a result, any messages sent to this endpoint will not be delivered.

Exploring the Issue

What Does 'EndpointDisabled' Mean?

The 'EndpointDisabled' error occurs when an endpoint, such as a mobile device or an email address, is marked as disabled in AWS SNS. This can happen for various reasons, such as the endpoint being unsubscribed or the device being inactive for a prolonged period.

Common Causes

  • The endpoint was manually disabled by an administrator.
  • The endpoint has been inactive for an extended period.
  • There were too many failed delivery attempts to the endpoint.

Steps to Fix the 'EndpointDisabled' Issue

Step 1: Verify the Endpoint Status

First, check the status of the endpoint in the AWS SNS console. Navigate to the AWS SNS Console and select the relevant topic. Under the 'Subscriptions' tab, locate the endpoint and verify its status.

Step 2: Enable the Endpoint

If the endpoint is disabled, you can enable it using the AWS CLI. Run the following command to set the endpoint's attributes:

aws sns set-endpoint-attributes --endpoint-arn --attributes Enabled=true

Replace <your-endpoint-arn> with the actual ARN of your endpoint.

Step 3: Create a New Endpoint

If enabling the existing endpoint does not resolve the issue, consider creating a new endpoint. Use the AWS SNS console or CLI to create a new subscription and endpoint.

Additional Resources

For more detailed information on managing endpoints in AWS SNS, refer to the AWS SNS Developer Guide. Additionally, explore the AWS SNS FAQs for common questions and troubleshooting tips.

By following these steps, you should be able to resolve the 'EndpointDisabled' issue and ensure that your notifications are delivered successfully.
