Yesterday 2019-04-07 I was canceling Webflow.com hosting which was with a certificate. When I was done and moved to new hosting zenbox.pl I tried to issue the certificate through them but I was getting the same error back.
I have an option to manually add SSL but I can’t access the existing certifications nor can I create a new one. I’m in a loop
What can I do ?
Can I prove that I own the domain and get access to those existing somehow? or revoke/ delete them and issue a new one ?
Nope, Let's Encrypt doesn't ever possess users' private keys—they exist only on your own server. If you don't have appropriate access to the server or if the private key has been deleted, there's no way that we can get you access to the private key.
Also, as our rate limits page explains,
Revoking certificates does not reset rate limits, because the resources used to issue those certificates have already been consumed.
You'll need to wait a week, or issue a certificate containing a different combination of names, or request a certificate from a different CA.
You could add an extra subdomain like example.dinapolilevels.com; in that case this rate limit wouldn't prevent the issuance of the certificate for all three names.
I've never used it, but I know Buypass Go SSL is a free publicly-trusted certificate provider that's compatible with the ACME protocol that Let's Encrypt uses.
Thank you for the idea of using another CA. In the end I used cloudflare.com and their shared SSL that comes with a free plan. Website https://dinapolilevels.com/ is secure again
