I already have this problem on the third website. I don't know why, but suddenly I have denied access from one specific IP address, from other addresses it works. This address is not in the blacklist. Is it entered elsewhere or what might be causing it?
There should be a log entry (maybe marked as "read") when the firewall blocked you. You can't add your own IP managing lists, so the only option that automatically adds your IP to blacklist is the "URL inspector".
Nothing. In firewall log there is not my own IP address. As I say, this is the third website, where I am in Blacklist, with no entry in the firewall. I didn´t do anything with this website for 14 days and now I´m blacklisted...
What is URL inspector?
Do you have my other extension Control Center? With that extension and the "Control Center Connect" plugin each IP added to any of your managed websites will be automatically added to all your managed websites.
The url inspector is a feature of the firewall that allows to block any ip trying to access to some specific resources (for instance Wordpress admin page). You can find it into Waf configuration -> url inspector tab.
