Troubleshooting CSF firewall configurations via Security page

POSTED BY: csf_warden ACTIVE_MEMBER POSTED ON: Jun 22, 2026 CATEGORY: GENERAL

I accidentally blocked port 80 in my custom firewall settings. Now all websites are offline. Can I fix this without SSH?

Yes, navigate to **Security -> Firewall** -> open the **Port Configurations** tab -> find TCP_IN/TCP_OUT fields and ensure `80,443` are in the list -> click **Save and Restart CSF**. The firewall daemon will reload and restore access.
