CrowdStrike technical troubleshooting guide
Use these safe checks to describe and triage common technical problems. Avoid disabling endpoint protection or changing security policies as a workaround; involve your security administrator for sensor and detection issues.
Identify the affected component
- Determine whether the issue involves the Falcon console, endpoint sensor, authentication, connectivity, installation, updates, or a security detection workflow.
- Record the affected operating system, device count, time of occurrence, and exact error message.
- Check whether the issue is isolated to one endpoint or affects multiple users and devices.
Safe troubleshooting checks
- Confirm that the affected device has a stable network connection and correct system date and time.
- For installation issues, confirm that the device meets the requirements and that deployment is being performed through an approved method.
- For update problems, check whether a managed rollout or maintenance window is in progress.
- For connectivity issues, ask the network or security team to review approved network paths and policy controls.
- For Windows, Mac, server, or cloud security issues, use product-specific official documentation and administrator guidance.
