SNS message delivery to a subscription endpoint failed due to disabled endpoint, permission issues, or endpoint errors.

generic

88% success Enable delivery status logging to identify the specific failure reason
```
Configure delivery status logging in SNS topic attributes, then check CloudWatch Logs for delivery failure details
```
Sources: https://docs.aws.amazon.com/sns/latest/dg/sns-topic-attributes.html
85% success Re-enable disabled endpoints or resubscribe for platforms like SQS, Lambda, HTTP
```
aws sns set-subscription-attributes or delete/recreate the subscription for the failing endpoint
```

Common approaches that don't work:

Republish the same message repeatedly to a disabled endpoint 95% fail
Disabled endpoints reject all messages; republishing without re-enabling won't help
Delete and recreate the SNS topic to fix delivery issues 80% fail
Recreating the topic loses all subscriptions and requires reconfiguring all subscribers
