port 2304 failed

Hi team, I have this issue

[root@cwp ~]# sh /scripts/check_api
User API port 2302 check: OK
Oauth query check: OK
User API folder check: OK
External API port 2304 check: OK
External API files and htaccess : OK
CSF Firewall status check: ENABLED
TCP_IN for port 2304 set in /etc/csf/csf.conf: FAILED
TCP_OUT for port 2304 set in /etc/csf/csf.conf: FAILED

How can I resolve tht.

Open the ports in the CSF Firewall config file?

Thanks for your help GTMAN
