What is the name of the domain?
Many domains
What is the error message?
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
What is the issue you’re encountering
Universal SSL is enabled, but the Edge Certificate does not exist
What steps have you taken to resolve the issue?
I am a company managing many domains—over 30,000—and I have been facing a silent issue. It appears that several domains, which previously had Universal SSL enabled and were properly certified, suddenly stop working. Upon investigation, I find that Universal SSL is still enabled, but the Edge Certificate is missing, causing the error mentioned in the title.
Is there a way to prevent this from happening or to fix it—either permanently or as a temporary workaround—via the API?
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?
