May I ask in the meantime have you tried disabling the Unviersal SSL, wait for some minutes, therefore re-enable it to re-generate the SSL certificate? :thinking:

May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

Are you planning to conect a custom domain? Is it already connected?

Thanks for the reply but I don’t see anywhere to disable universal SSL for the pages.dev domain.

I have connected a custom domain and that works fine, including the main pages.dev domain. The issue lies when trying to preview deployments.
