Cache and Configuration Persistence After Domain Removal from Cloudflare

[atsushi.hagihara]

What is the name of the domain?

jwglb9c5e1dk2k.jp

What is the error number?

N/A

What is the error message?

No specific error message. The issue is that the server: cloudflare header persists for a domain that has been removed from Cloudflare.

What is the issue you’re encountering

After removing my domain from Cloudflare and updating DNS settings with a new provider (XserverDomain), I noticed that tools like redirect checkers and Google Search Console still show server: cloudflare in the server response headers. This suggests that Cloudflare’s cache or settings might still be affecting the domain.

What steps have you taken to resolve the issue?

1. Removed the domain from Cloudflare via the dashboard.
2. Updated the DNS settings on my new provider (XserverDomain) to ensure proper redirection.
3. Verified that no Cloudflare-specific DNS records remain in the current DNS setup.
4. Checked Cloudflare’s documentation and community forum for guidance but couldn’t find a definitive solution.

What feature, service or problem is this related to?

DNS records

What are the steps to reproduce the issue?

1. Use a redirect checker or server header inspection tool (e.g., curl or an online redirect checker).
2. Check the response headers for the domain xn--u9jwglb9c5e1dk2k.jp.
3. Observe that the server: cloudflare header is still present, even though the domain has been removed from Cloudflare.

You are using Hubspot as your host…

Hubspot themselves use Cloudflare which is why you see Cloudflare headers.

Thank you for your prompt and insightful response!

I now understand that the server: cloudflare header is appearing because HubSpot, as my hosting provider, uses Cloudflare internally. This clarification greatly helps in resolving my confusion about the headers and ensuring my setup is functioning as expected.

I truly appreciate your guidance and the tools you provided to verify this. It’s great to see such an active and helpful community. Thanks again!
