Deceptive site ahead error in pages.dev

I have created a simple Next.js app and linked the Cloudflare Pages to the app code. Whenever I access the site (dashboard-4jr.pages.dev) get a Deceptive Site Ahead error.

I thought that all subdomains of pages.dev (part of Cloudflare I guess) would automatically the SSL settings in place.

Or, is there something I am missing?

Thanks
