Persistent CSF-Related 500 Error on AlmaLinux 9 After CyberPanel Update

I have a problem logging into the panel. I’m receiving a 500 error. The issue is related to CSF. After uninstalling CSF, the system works fine. When I perform a CyberPanel update, the system starts working properly again, but only until the end of the day. At night, it stops working again. This problem has been ongoing since last year. When I received information from you that the issue had been resolved, I performed an update — the system worked properly for a few days, but then the problem returned.

The system is AlmaLinux 9. Will the issue with CSF finally be resolved permanently?

I have the same problem. Updated to Ubuntu 22.04.5 & cyberpanel to latest version and everything worked, but the next day the “500 Internal Server Error” appeared again and ssh as “operation time out”.

same here on 2 servers running alma9. cp update command fixes it temporarily, same issue a few hours later.

also both servers have this issue:
[root@cp ~]# dnf update -y
