My web server is (include version): nginx

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

I updated the A record to ‘18.104.22.168’ still https://check-your-website.server-daten.de/?q=ercmn.org shows ‘22.214.171.124’ and hence it seems certbot is failing. Can you please help?
where did you update that record? Now I see the 104.* address. But Letsencrypt has seen the 3.14.*
There is no older Letsencrypt certificate listed, the CT-part shows only the
|CloudFlare Inc ECC CA-2
||*.ercmn.org, ercmn.org, sni.cloudflaressl.com
Looks like you use the integrated Cloudflare solution to have a SSL connection between your server and Cloudflare. Then you don't need an own Letsencrypt certificate.
Checking your raw ip there is another certificate - https://check-your-website.server-daten.de/?q=126.96.36.199
expires in 18 days *.careerleaf.com, careerleaf.com - 2 entries
PS: Oh, there are some different informations.
There you use
ercmn.org, not the
There is a check of the
educatemn.org - https://check-your-website.server-daten.de/?q=educatemn.org
That domain has the 3.14.* ip address. But there is the error:
Domain is not defined.
Looks like your vHost setup is incomplete.
What command did you run? What was the complete output? What ACME client are you using? What version of it?
There was an error with dns records. www routing was also added as an ‘A’ record and hence error. Removing it solved the issue.
Thank you guys for your apt response. Really appreciate it.
But if you have a main domain, it's better to have a DNS entry and a correct configured vHost with one certificate and both domain names. And correct redirects.
Some users add always
www to the domain name.
