Hetzner blocked by CSF?

[joans]

Hello,

I have a VPS hosted by Hetzner, with Almalinux 8 and Webuzo control panel.

I disabled firewalld and I installed CSF via Webuzo.

I had many trouble to configure it.

In the Webuzo/Security/IP block list, I have many times these address blocked:
- 185.12.64.2
- 185.12.64.1
- 0.0.0.0

I doesn't affect the usage of my website, but I do not understand what is the reason.

These address are the recursive DNS of Hetzner and they should not be blocked.

Therefore I whitelisted them from CSF and LFD.

But still, there are blocked on webuzo.

When i disable CSF firewall, the IP are not appearing in the IP block list.
When i enable CSF firewall, the IP immediatly appeared as blocked.

I conclued that this problem comes from CSF configuration?

note: IP is not in the denied list.

I have asked at Webuzo forum and the answer was that I need to find help directly from CSF.

As I am not an expert, it is hard to find some solution to this problem. Thanks for any help.

Could it be a conflict with OpenLiteSpeed?
