Solutions to frequently encountered issues.
Check shows "Unknown" status
A check starts with an unknown status and will update to up or down after the first execution cycle. If it stays unknown:
- Ensure your team has a positive credit balance.
- Ensure the check is active (not paused).
- Check that at least one agent is assigned to the check.
False "Down" alerts
If a check flickers between up and down:
- Whitelist agent IPs — your firewall or WAF may be blocking agent requests. See How to Whitelist Our Agents.
- Increase the interval — if your server rate-limits requests, a 30-second interval may trigger throttling.
- Check expected status — if your server redirects (301/302), make sure the expected status matches.
Credits depleting faster than expected
Credit usage depends on: number of active checks × (60 / interval_seconds). To reduce consumption:
- Increase check intervals (60s → 300s reduces consumption by 5×).
- Pause checks you don't actively need.
- Remove duplicate checks.
Notifications not received
- Verify the webhook channel is enabled (not disabled).
- Use the Test button on the notification channel to verify the webhook URL is valid.
- Ensure you (or the webhook) is assigned as a recipient on the specific check.
- Check your Slack/Teams channel — the notification may have been delivered to a different channel than expected.
Cannot create checks (403 Forbidden)
Only team admins can create, edit and delete checks. If you have the viewer role, ask a team admin to upgrade your permissions.
