New certificate for the same domain

My domain is:

I ran this command:

Short version: I deleted a certificate and want a new one for the same domain.
Long version: I used a Disk Station Manager from Synology to create a SSL-Certificate. I closed the port 80 what might have resulted in an unsuccessful auto renewel. Since I was not sure how to renew it, I deleted the certificate from the Disk Station Manager to create a new one and forgot about the domain name limitation.

So, is it possible to recreate a certificate or get a new one for the same domain after revoking the old one or something?

I have hope since I found this tip in the Synology manual

You can only register for a limited number of certificates per domain from Let’s Encrypt. If the limit is exceeded, enter the current domain name as the Subject Alternative Name (SAN) and use another domain name for certificate request.

It produced this output: -

My web server is (include version): -

The operating system my web server runs on is (include version): -

My hosting provider, if applicable, is: -

I can login to a root shell on my machine (yes or no, or I don’t know): no

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
DSM 6.2.2-24922 Update 4
on RS816 (Model Name) from Synology Inc.

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): -

Thank you for your valuable time!

Hi @DopingAnt

please read

Deleting / revoking certificates without a reason is always wrong.

I take all the blame on me due to my ignorance about the renewel process. The link didn’t provide me new information though.

So is it possible to get a Let’s Encrypt certificate for my domain in any way again? Maybe through the usage of a private key or csr (in the case I find it?)
