AutoSSL from LetsEncrypt giving error with Cloudflare
Was the site working with SSL prior to adding it to Cloudflare?
Yes
What is the current SSL/TLS setting?
Full
What are the steps to reproduce the issue?
I have a very old website. When SSL became a thing, I used LetsEncrypt to handle the SSL. Recently we started getting DDoSed and I added Cloudflare to mitigate it.
Since doing so I’m now getting an error from AutoSSL:
(I’ve removed URLs because it wont let me post them on account of being a new user)
AutoSSL did not renew the certificate for “(URL)”. You must take action to keep this site secure. The “LetsEncrypt” AutoSSL provider could not renew the SSL certificate without a reduction of coverage because of the following problems:
(URL) (checked on Jun 9, 2026 at 12:42:48 AM UTC)
DNS DCV: No local authority: “(URL)”; HTTP DCV: The system queried for a temporary file at “(URL)”, but the web server responded with the following error: 403 (Forbidden). A DNS (Domain Name System) or web server misconfiguration may exist. The domain resolved to an IP address “(IP address)” that does not exist on this server.
How can I resolve this? I don’t really know much about SSL or Cloudflare so looking for a minimal fix to get this working again.
