Use the following troubleshooting steps when there are
Cylanceapplication call errors or when no results are found.
- Ensure at least one tenant configuration has been populated, otherwise an error 500 page will be shown when trying to access the web application. In QRadar,Settings > Admin > CylancePROTECT and CylanceOPTICS. Make sure at least one tenant configuration is present.
- Ensure communication with theCylancetenant is successful. When creating or editing a tenant configuration, a test connection is made when the configuration is saved. Pay attention to the result notification as it would clearly indicate whether communication is successful.
- Ensure proper network configuration. Ensure port is open to communicate over port 443 (i.e. HTTPS). Make sure no network or host firewalls are blocking traffic over this port.
