Rocky System problems

[SouthWind017]

Hello everyone
cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)

cat /etc/redhat-release

Rocky Linux release 8.8 (Green Obsidian)
My server version is 4.5, the operating system is centos7.8, and the client operating system is rocky 8.8. Does the client support vulnerability detection, brute force attacks, and proof-of-concept guidelines? After I set it up, the vulnerability detection was not recognized. I downloaded the offline package and modified the corresponding system, but it still didn't work.
