Troubleshooting
Learn how to troubleshoot potential Uptime Monitoring problems.
This feature is only available if your organization has enabled early adopter features. Early adopter features are still in-progress and may have bugs. We recognize the irony. If you’re interested in participating, enable early adopter features in organization settings.
Uptime alerts are only available for organizations that have early adopter features enabled. They must also have URLs that match our auto detection criteria. In the current version, organizations are limited to a single uptime alert.
Some hosting platforms can block incoming requests from Sentry's Uptime Bot, falsely triggering uptime alerts. 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.
Our uptime check requests use the following User-Agent:
Mozilla/5.0 (compatible; SentryUptimeBot/1.0; +http://docs.sentry.io/product/alerts/uptime-monitoring/)
See IP Ranges for a complete list of IP addresses used for uptime checks.
Uptime alerts create downtime issues. If you're not receiving notifications when downtimes are detected, make sure you've properly configured an issue alert with the issue category "uptime".
