Domain Seems to have been blocked by csf upgrade

[ronbrigman]

Hi,

I am using Cpanel on CENTOS 6.8 VMWare.
csf is set to auto update.

I could not find the upgrade logs for csf. But last week an issue began to happen.
My domian does not work with the www added when connecting from inside the same network as the VM / webserver.

When I test with csf "disabled" it works just fine.

I am assuming this was caused by an update?
I don't know how to fix it.

Thank you,

is there some way to roll back the latest upgrade?
for sure i will not be using automatic updates moving forward this problem completely blindsided us
for now, I can only remove CSF and try some other firewall software until some resolution to this very serious problem found
