Hello,

I am experiencing an issue with my website when using Cloudflare. The site works perfectly fine when I pause Cloudflare, but when I enable it, the site shows as down, and the error message indicates that the server host is down.

I have verified that my server is up and running, and there are no issues on the hosting provider’s end. Could you please assist me in resolving this issue?

Thank you for your help.

I get error 1016 from your site which most likely means that your DNS record is a CNAME and what it is pointing to does not resolve.

Can you show a screenshot of your DNS records page here…
https://dash.cloudflare.com/?to=/:account/:zone/dns/records

Include the 2 Cloudflare nameservers at the bottom of that page. Your domain is set to use nameservers kip and rosa but another pair are being reported by the registry and a further pair are likely the active ones.
https://cf.sjr.org.uk/tools/check?cb85f5cd67a54970b322b32d8cb5f499#dns

You may be in the wrong account for your domain, or have deleted and re-added the domain several times which will change the nameservers.

(Getting mix of 521 and 1016 so something is messed up, you need to ensure the correct nameservers are set).
