**VERIFICATION / TROUBLESHOOTING**
* If the sensor does not link properly:
* Re-check the outbound TCP 443 access to [sensor.cloud.tenable.com](http://sensor.cloud.tenable.com) and [plugins.nessus.org](http://plugins.nessus.org).
* Make sure the Linking Key is correct and not expired.
* If the scans do not find hosts:
* Confirm that the scanner can reach the target network (routing, security groups/NSGs, and target host firewalls).
* For credential scans, confirm that the credentials work and the required auth ports are reachable.
