We’re sorry, you are not allowed to proceed

Hi
1st of all: I love this plugin!
But…

Very often I have this problem:
– I go to my wordpress login page, let’s say https://www.mywebsite/mycustomloginpage.php
(the name of the login page was previously set into the “personalized login page settings”, having also set to true the option “disable wp-login-php”)
– Suddenly I receive the message “We’re sorry, you are not allowed to proceed”

This happens VERY often, let’s say almost every morning, the 1st time I attempt to login to wordpress.

So, being locked out, what do I do?
I connect to the website via FTP, rename the wp-cerber plugin folder and then attempt to login to wp-login.php.
It then login to wordpress, go back to the ftp client and rename the wp-cerber folder to its correct value.
Once logged in, everything works great.

So, this is very frustrating, 1st of all because I have to do it every morning for every website I manage.

This behaviour shas started since a few weeks, with one update you released.
Now, maybe it’s some settings on my side that is wrong, but I assure you I did not touch a settings, but the two I wrote about above here.

Any idea of what should I do in order to make the plugin work as intended?

Each of the websites having this problem are NOT receiving huge traffic, it’s like 50 users a day, with very low (or none) suspect activity.
