This merely indicates that the firewall blocked an incomming connection to a specific port, for a specific IP. I believe you can disable logging somehow if you want to stop getting the messages.

Don't mind it. Its just the firewall logging blocked traffic.

This means that CSF is doing it's job
If you do want to disable the logging, I believe you can find it under this variable inside the config:
# Enable logging of dropped connections to blocked ports to syslog, usually # /var/log/messages. This option needs to be enabled to use Port Scan Tracking DROP_LOGGING = Default: 1███ Autumn Networks
