# Troubleshooting

## Beacon isn't responding to @mentions

1. Make sure Beacon has been invited to the channel: `/invite @Beacon`
2. Check that the OpsBeacon Slack app is still installed: **Slack Settings → Manage Apps**
3. Try a simple test: `@Beacon hello`

If Beacon still doesn't respond, contact [support@opsbeacon.co](mailto:support@opsbeacon.co).

## "AWS connection failed" error

1. Verify the IAM role still exists in your AWS account
2. Check that the External ID in the trust policy matches the one on your OpsBeacon settings page
3. Confirm the role has the required permissions (see [AWS IAM Permissions](https://docs.opsbeacon.co/security-privacy/iam-permissions.md))

Run a connection test:

```
@Beacon test AWS connection
```

## Cost data shows \$0 or seems wrong

* AWS Cost Explorer data has a \~24h delay. Check if the period you're asking about is within the last 24 hours.
* Confirm Cost Explorer is enabled in your AWS account (it requires a one-time activation in the AWS Console)

## Trusted Advisor recommendations not showing

This requires a Business, Enterprise On-Ramp, or Enterprise AWS support plan. On Developer or Basic plans, Trusted Advisor check details are not accessible via API.

## GuardDuty findings not appearing

1. Confirm GuardDuty is enabled in the regions you care about
2. If no findings appear after enabling GuardDuty, it may simply mean no threats have been detected — this is expected behavior

## Security Hub findings not appearing

Confirm Security Hub is enabled and has at least one security standard enabled (e.g., AWS Foundational Security Best Practices).

## Contact support

For anything not covered here: [support@opsbeacon.co](mailto:support@opsbeacon.co) or mention `@Beacon help` in Slack.
