Hi everyone, I created an SSL certificate for my domain (nloi-Nextcloud.de) using Nginx. Unfortunately, I made a mistake and locked myself out of the server where Nginx was installed, so I need to reinstall it.
Now my question is: Is there any way to remove the certificate from my domain? I can't create another one using the new Nginx installation because of the following error: "Domain Nloi-Nextcloud.de is already in use."
Thanks a lot for your help
Hi @Noah3648,
Just a quick thought.
Is the “machine” nginx was (is ?) still up and running? Is so shut it down before trying on the new “machine”.
I don't think so, as I said, I had to reinstall the server because I couldn't access it anymore.
Did the original server get stopped and uninstalled?
What produced that error? You didn't specify the ACME client used or any other required information for us to help you. So:
When you opened this thread in the Help section, you should have been provided with a questionnaire. Maybe you didn't get it somehow (which is weird), or you've decided to delete it. In any case, all the answers to this questionnaire are required:
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
I ran this command:
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):
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
My domain is: nloi-Nextcloud.de
I ran this command: create ssl certificate at nxinx
It produced this output: domain nloi-Nextcloud.de is already in use
My web server is (include version):
The operating system my web server runs on is (include version): Ubuntu 24.04
My hosting provider, if applicable, is: Ionos
I can login to a root shell on my machine (yes or no, or I don't know): yes
Can you maybe include a screenshot? I don't know what these mean. Did nginx add an ACME client at some point?
Are you sure that's nginx? It looks like Nginx Proxy Manager which is not the same as nginx.
Oh Sorry, yes its Nginx Proxy Manager. I didn't know there was anything else here
Nginx Proxy Manager is its own thing, and many people here have found it hard to diagnose. Like you're seeing, it seems to be telling you an error message without telling you what's really wrong or how to fix it. Your problem isn't actually with getting certificates (which people on the forum can generally help with), but with how to configure NPM. It may be that someone else on this forum will be able to point you in the right direction, but I certainly can't myself, and you may want to look into some support places that are more specific to NPM. (At least, if you want to continue using NPM. Depending on what your actual goals are in setting it up, there may be other software which is easier to use and better at helping you diagnose problems.)
