Csf & directadmin ssl renew problem

Help
1

I use directadmin and csf.
While CSF is active, SSL is not renewed. I’m getting an error.
If I close the csf, the processes complete without any problems.

Yes, it is open. I have been using it for years, but it has been error for the last 2 weeks.

Can you confirm access to port 80:
with CSF on?
with CSF off?

yes 80 port open. All websites are accessible. With or without www.

You must be missing something or CSF is actually breaking something.

Using the name above, I can’t access HTTP nor HTTPS.
You must have some sort of GeoLocation blocking in place.
