Cannot Renew Let's Encrypt Certificates Due to DNS Issues and Inaccessible Plesk Account

[XelaNuarb]

I have been getting the following email for about 1-2 years. And I dont know how to get rid of it.
I tried contacting my former hoster and he refered me here. Further I have no Idea what or where I would have set whatever this is up. And therefore am neither able to turn it of or login anywhere since I dont know the username/password it mostlikely.
Please someone help me with this...

Welcome @XelaNuarb but I'm not sure how much help we can be.

Let's Encrypt issues certificates only when requested by some software client.

In this case it looks like a Plesk system. We don't have access or knowledge of what that system is. There are hundreds of ways to request LE certs.

I can see from the public cert logs that you got 3 certs in 2021 and 2022

What services did you subscribe to back then where you requested these certs? That is the place you need to resolve this. You have to disable the cert request on that service or system.

I can see why the cert request fails. That domain name is not currently registered.

Another option is to setup a rule in your mail system to auto-delete this reminder email. It would be best if you can disable the faulty request though so you don't waste Let's Encrypt resources.

Your domain xela-nuarb.at appears to no longer be registered. You cannot obtain a certificate for a nonexistent domain.

% whois  xela-nuarb.at

% nothing found

Yes, it sounds like what happened is this user used to have that domain name, stopped hosting it and let it expire, but there's still something on the hoster's system attempting to renew a certificate for it. Since that of course won't work, that client is emailing the user the problem.

But I have no idea why the hoster would try to refer the user here, there's nothing we can do and that email isn't coming from Let's Encrypt's systems.

@petercooperjr

that email isn't coming from Let's Encrypt's systems.

Yes, I forgot to mention that essential bit of info

[XelaNuarb]

Hey, I would love to do that, unfortunately I have no Idea where I subscribed...

You may benefit from examining the email headers to determine its origin, but as others have already indicated, the email does not come from Let's Encrypt, which leaves us unable to assist.
