# Uptime Monitoring Troubleshooting | Sentry Docs

## [Stop Unwanted Uptime Checks](https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/troubleshooting.md#stop-unwanted-uptime-checks)

If you receive unexpected uptime check requests, the monitor may have been [created automatically](https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/automatic-detection.md). Delete the monitor from the [Monitors](https://sentry.io/monitors/) page to stop future checks. An automatically detected monitor will not be re-created after you delete it.

If you cannot delete the monitor immediately, you can block requests that use the `SentryUptimeBot` User-Agent shown below. Blocking requests does not itself disable the monitor. Delete or disable it in Sentry to stop its checks.

## [Verify Firewall Configuration](https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/troubleshooting.md#verify-firewall-configuration)

Some hosting platforms can block incoming requests from Sentry's Uptime Bot, falsely creating uptime issues. We recommend verifying your firewall configuration to ensure incoming requests from Sentry are allowed.

If you need to configure your firewall allowlist to include Sentry's Uptime Bot, we recommend checking against our `User-Agent`, given that our IP addresses can change without notice.

### [User Agent](https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/troubleshooting.md#user-agent)

Our uptime check requests use the following `User-Agent`:

```bash
SentryUptimeBot/1.0 (+https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/)
```

### [IP Addresses](https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/troubleshooting.md#ip-addresses)

See [IP Ranges](https://docs.sentry.io/security-legal-pii/security/ip-ranges.md#uptime-monitoring) for a complete list of IP addresses used for uptime checks.

## [Verify That Alerts Match Downtime Issues](https://docs.sentry.io/product/monitors-and-alerts/monitors/uptime-monitoring/troubleshooting.md#verify-that-alerts-match-downtime-issues)

Uptime monitors create downtime issues. If you're not receiving notifications when downtimes are detected, make sure you've [configured an Alert](https://docs.sentry.io/product/monitors-and-alerts/alerts/create-alerts.md) whose sources and filters match those issues, with actions for the channels you expect.
