4xx errors of --> 249.6k. (last 7 days)

We noticed that for the last 7 days 4xx errors of → 249.6k.

This sounds bad and it sounds like a lot.

We tried to dig into the cloudflare analytics to understand what it is and what is causing it - and especially how to solve it. In addition with the community we also did not find any clear directions.

Our sites all are up and working - perhaps we are missing something. Some stats →

Can you please assist us on this matter?

Maybe some crawler tried accessing some paths with strange queries or even some attack probing?
