It appears to be a known issue with letsencrypt-vesta: [https://github.com/interbrite/letsencrypt-vesta/issues/51](https://github.com/interbrite/letsencrypt-vesta/issues/51) Since letsencrypt-vesta has not been updated in over 2 years, you might consider using the built-in support VestaCP offers for Let’s Encrypt, which is suggested in this comment: [https://github.com/interbrite/letsencrypt-vesta/issues/51#issuecomment-372905254](https://github.com/interbrite/letsencrypt-vesta/issues/51#issuecomment-372905254) ---

Hi @dosdemil.es > [@dosdemil.es](#): > > My domain is: cosmetica.dulcecalvo.es the error says, that your website sends the wrong user key. Your config ( [https://check-your-website.server-daten.de/?q=cosmetica.dulcecalvo.es](https://check-your-website.server-daten.de/?q=cosmetica.dulcecalvo.es) ): | Domainname | Http-Status | redirect | Sec. | G | | --- | --- | --- | --- | --- | | • [http://cosmetica.dulcecalvo.es/](http://cosmetica.dulcecalvo.es/) | | | | | | 46.183.114.223 | 200 | | 0.873 | H | | | | | | | | • [http://www.cosmetica.dulcecalvo.es/](http://www.cosmetica.dulcecalvo.es/) | | | | | | 46.183.114.223 | 200 | | 0.123 | H | | | | | | | | • [https://cosmetica.dulcecalvo.es/](https://cosmetica.dulcecalvo.es/) | | | | | | 46.183.114.223 | 301 | [https://oidococina.online/](https://oidococina.online/) | 1.877 | N | | Certificate error: RemoteCertificateNameMismatch | | | | | | | | | | | | • [https://www.cosmetica.dulcecalvo.es/](https://www.cosmetica.dulcecalvo.es/) | | | | | | 46.183.114.223 | 301 | [https://oidococina.online/](https://oidococina.online/) | 1.644 | N | | Certificate error: RemoteCertificateNameMismatch | | | | | | | | | | | | • [https://oidococina.online/](https://oidococina.online/) | 200 | | 7.627 | B | | | | | | | | • [http://cosmetica.dulcecalvo.es/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de](http://cosmetica.dulcecalvo.es/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de) | | | | | | 46.183.114.223 | 200 | | 0.117 | | | | | | | | | • [http://www.cosmetica.dulcecalvo.es/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de](http://www.cosmetica.dulcecalvo.es/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de) | | | | | | 46.183.114.223 | 404 | | 0.120 | A | | Not Found | | | | | Your website redirects to oidococina.online, but your cosmetica sends a status 200 checking a file under /.well-known/acme-challenge. Oh - what's that? Opening ```nohighlight http://cosmetica.dulcecalvo.es/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de ``` the content is ```nohighlight check-your-website-dot-server-daten-dot-de.VJiX50xcNEOMO6eyxr0aZq7LaciOJUXmNVBNj7Qfzyw ``` So your webserver puts the random file name in the file and adds the key. Is this the key of your hoster? ---
