Challenge request every 3-5 minutes

Hi there,
recently i’ve moved to “under attack” for various reasons. In the beginning i had my website set to recheck every 2 hours for browser validation but recently moved to a day. What i have noticed is that the browser checks occurs every 3 to 5 minutes for some reason, although it’s clearly stated 1 day. I’ve tried different options but the challenge is still 3-5 minutes. I have no ideea what is going on, i didn’t had any recent changes in any of my scripts or Cloudflare settings, it’s just doing this and even if i’m setting it for a month, it’s still challenges me … At this point i don’t know what to do anymore and seeking advice.

Thanks in advance.

Are you using and browser privacy or ad-blocker extensions? They might be messing with the cookie CF sets.

No. I have ublock but obviously disabled on my websites. I’ve talked with people (visitors) and this keeps going even if no extensions are even installed.

Can you share the domain?
