After upgrading a vulnerability scanner, tickets are not being created; what is the most likely cause and fix?

• A. There was an IP change to the VM. Make changes to the server properties.
• B. The upgrade has a bug. Reboot the server and attempt the upgrade again.
• C. The vulnerability scanner is on a different subnet. Open the ports, and it will reconnect.
• D. There is an application compatibility issue. Roll back to the previous working backup.

Answer: (D)

Upgrading a vulnerability scanner can change how it talks to downstream systems, like the ticketing/incident workflow. If tickets aren’t being created after an upgrade, the most likely cause is a compatibility issue between the new scanner version and the existing ticketing integration or automation logic. Rolling back to the previous working backup restores the known-good state of that integration, quickly reinstating normal ticket generation and providing a stable baseline to diagnose what changed in the upgrade. Once you’re back on the working version, you can check release notes for breaking changes, test the upgrade in a staging environment, and implement any required configuration or patch steps before reattempting the upgrade. The other options point to network or reboot problems that would typically manifest as broader connectivity failures rather than specifically stopping ticket creation.
