I have a problem with cloudflare with my client

a problem when our customers refresh their pages , they have a block when the session expires they lose the form they have already entered. they are forced to do the form again, even though the old form is saved, in this case they will lose money .
can you please verify and check this problem .
my domain is centurioninvest.com
my mail {redacted}

At first sight, I got Browser Integration Check.
Furthermore, are you using www or non-www version of your Website?

May I ask is this some kind of a captcha form due to Security measurements being enabled and active on the Website or a login form at a Webpage, etc.?
