Website checking my browser

Hi folks,

I’m stuck on the following issue :
I’m trying to WPT the following website https://www.oscaro.com (not mine)
You can see HERE the results.

I have noticed that the website have used a Cloudflare feature to protect against DDOS attacks.
And I would expect WPT to wait and measure perfs after the redirect operates.

Is there a way I could do this ?

Thanks
