I am using a fatal error captcher plugin and noticed that I am getting several errors on IPDenyList.php.
As I can see it is blocking a specific ip number, which I have add to the IP deny list. So I assume it is working, but maybe there is an issue on your IPDenyList.php file as well.
Error message data:
E_ERROR:1 0: An empty key isn't allowed in file: /var/www/vhosts/waterpijp-bong.nl/domains/waterpijp-bong.nl/public_html/plugins/system/admintools/src/Feature/IPDenyList.php line: 120
