Does it work when you change the DNS record to DNS-Only?

Edit: The site does work for me.

Hello @Laudian I have the records at Proxied.

You mean you’re able to access the domain, and not getting the Cloudflare host down page?

Man, this is sad. Couldn’t find a button to open a ticket in the support portal either.

When did your go down?
