Scan error message “Vulnerability Scan”

I searched the documentation and forums for this,

I searched forums and documentation but didn’t find a solution. Yes, I found a solution!

When I ran scans, I always had the yellow warning triangle for Server State and Vulnerability Scan.
I was able to find the solution with Server State, but with Vulnerability Scan I couldn’t find a solution to fix the problem.
Question, can someone help me solve this problem?
If so, thank you very much!!!
