After joining Cloudflare my Vercel application does not work

[user20422]

Hello all,

I had a fully working domain with the DNS config on namecheap and it was deployed on Vercel (certificate deployed by them as well). Now I have joined Cloudflare and I get the error:

The page isn’t redirecting properly

An error occurred during a connection to guzman.dev.

This problem can sometimes be caused by disabling or refusing to accept cookies.

What is it going on? I do not understand well. My DNS looks like this:

type: A name: domain.dev content: server ip proxied TTL auto
type: CAA name: domain.dev content: 0 issue letsencrypt.org  DNS only TTL auto
type CNAME name: www content: domain.dev proxied TTL auto

Thank you in advance and regards

Thank you! Indeed that helped, I had to enable SSL full strict because Vercel does not allow to disable HTTPS
