Troubleshooting Qualys

PROBLEM

SOLUTION

Agent host cannot reach the Qualys Cloud Platform (or the Qualys Private Cloud Platform if this applies to you) over HTTPS port 443. Check network access and be sure to whitelist the cloud platform URL listed in your account.

If the problem persists, attempt to set the cloud agent to scan on demand using the following steps:

1. Use Windows search to find the Registry Editor. Open Registry Editor as administrator. You will need to right click on the Registry Editor to get this option.
   
   

   Open

   

    

2. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Qualys > QualysAgent > ScanOnDemand > Vulnerability
   
   

   Open

   

    

3. Expanding the Vulnerability tab, you should see three 32-bit DWORDS:

   1. CpuLimit

   2. ScanOnDemand

   3. ScanOnStartup

      Open

      

       

4. Set ScanOnDemand to a decimal value of 1 by right clicking and selecting Modify. Ensure you select the Decimal option.
   
   

   Open

   
   1. Open

      

      This will initiate a scan right away.

   2. The data value will change to 2 when the scan is in progress.

   3. Open

      

      The data value will change to 0 when the scan is complete.
