How to Troubleshoot SentinelOne Not Working Issues
If a SentinelOne service or endpoint agent appears not to work, use these careful checks and involve your organization’s security team where needed.
Identify the issue
- Determine whether the problem affects the web console, a user sign-in, endpoint sensor status, or a specific security workflow.
- Record the exact error message, device name, operating system, and time of the issue.
- Check whether other authorized users or devices are affected.
Basic troubleshooting
- Confirm the device has a stable network connection.
- Restart the browser for a console issue, or restart the device only if permitted by your organization.
- Check for planned maintenance or an organization-wide service notice.
- Verify that the device date and time are correct, especially when authentication or certificates are involved.
Important security precautions
- Do not stop, uninstall, or tamper with endpoint protection to work around an error.
- Do not run scripts or commands from unverified forums or unsolicited support messages.
- Escalate suspected detection, sensor, or policy issues to your security operations team promptly.
