Resolve a timed out state
If a certificate issuance times out, Cloudflare tells you where in the chain of issuance the timeout occurred: Initializing, Validation, Issuance, Deployment, or Deletion.
To resolve timeout issues, try one or more of the following options:
Change the Proxy status of related DNS records to DNS only (gray-clouded) and wait at least a minute. Then, change the Proxy status back to Proxied (orange-clouded).
Disable Universal SSL and wait at least a minute. Then, re-enable Universal SSL.
Send a PATCH request to the validation endpoint
using the same DCV method (API only).
Follow the APEX validation method.
