My domain is: [nc.6lwpdtfk915u6acz.myfritz.net](http://nc.6lwpdtfk915u6acz.myfritz.net)

I ran this command: in WebUI nginx: Request a new SSL Certificate with Let's Encrypt.

It produced this output: [nc.6lwpdtfk915u6acz.myfritz.net](http://nc.6lwpdtfk915u6acz.myfritz.net) is already in use.

My web server is (include version): nginx-proxy-manager AppVersion: 2.12.3, Version 1.1.12

The operating system my web server runs on is (include version): TrueNas Scale ElectricEel-24.10.2

My hosting provider, if applicable, is: [myfritz.net](http://myfritz.net)

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

No; I lost access to it because I migrated my System from TrueNas Core 13.3 to the above Scale version and my current SSL Certificate for the domain is still active so I can't reuse that Name for my migrated system; is it possible to revoke the old certificate so I can renew it on my new system under the exact same domain name? Thank you.

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you're using Certbot): I don't have access to it anymore, so I don't know.

that's not a error of LE side: they allow duplicate certs up to 5/week.
