Disconnect with the my site!

Every half minute there is a disconnect with the site…
I turn off Cerberus and there are no disconnects, I turn on Cerberus and disconnections begin - registration on the site is lost and you have to log in again.
What is happening to it and how can I stop it?
My IP address does not change, it is the same and it is on the white list.
What should I do?

Othe problem - Cerber kill WP Rocket cach and site too slow load
How it can be resolve ?

What is Cerberus and how is it related to WP Cerber?

no need to nitpick about spelling, I’m asking about your plugin…
Wp cerber, I use a translator and it translated the name of the program a little crookedly, isn’t it obvious?
A serious problem is unsystematic disconnects with the site, sometimes authorization can be lost after 1-2 minutes, sometimes after an hour, sometimes more.
But there is no stable connection - a fact.
Before the previous plugin update, everything worked fine, now there is constant re-login.
If you disable the plugin, then there are no problems at all.

Can I wait for some answer or not?
