Have you set up AWS SNS but noticed that notifications aren’t being delivered? I’ve been there.
Here’s how I would troubleshoot it:
1️⃣ Check Subscription Status
-Login to AWS Console → Go to SNS → Topics → Subscriptions and verify if the endpoint (email, Lambda, SQS, etc.) is confirmed.
– If it’s in a “PendingConfirmation” state, confirm the subscription.
2️⃣ Verify SNS Topic Permissions
– Go to IAM → Policies and ensure your role has “sns:Publish” permissions.
– Without permissions, SNS won’t be able to send messages.
3️⃣ Confirm Endpoint Accessibility
– Check if the email, Lambda function, or SQS queue is active and reachable.
– If using Lambda, verify function permissions and logs.
4️⃣ Review CloudWatch Logs
– Go to CloudWatch → Logs → SNS Log Group and check for any errors or failed deliveries.
– Look for throttling, permission issues, or misconfigurations.
5️⃣ Test with AWS CLI
– Run:
aws sns publish –topic-arn arn:aws:sns:region:account-id:topic-name –message “Test message”
– If this fails, SNS may not be properly configured.
What other troubleshooting steps have worked for you?
