I have similar problem. I do not need to reboot but Data Center have to restart CSF.

It's highly unlikely that all IP addresses are blocked in iptables. If you have access isses, you need to check the following either from another network access or through the servers serial console port:

1. /var/log/lfd.log
2. iptables -L -n

Usually, it's because you've got yourself blocked by triggering something

In my case the server is down from all location, he need reboot , if i put all server IP on Firewall Allow IP is a solution?

On lfd log I don`t find any message about this IPs.

If there's nothing in lfd.log then it's unlikely to have anything to do with csf unless you've added the servers IPs to csf.deny or they are included in a BLOCK list netblock. lfd always logs all ip blocks.
