  • [comment u/nonlogin] the project has not been deployed to Cloudflare or validated in production.

  • [comment u/aaronkempf] what do you mean by 'running on cloudflare' lol. Kinda vague. BFD. I've got 110 domains on Cloudflare. Doesn't mean they are RUNNING ON CLOUDFLARE. Do you mean CloudFlare Workers? DynDNS? lol
