Hi @cmlaplata

checking your domain that can’t work - https://check-your-website.server-daten.de/?q=laveleria.com.ar

You use Cloudflare, so http is redirected to https, so the Apache authenticator can’t work.

And your certificate is expired, so Cloudflare can’t connect your webserver.

  • Use the Cloudflare integrated solution
  • Remove that Cloudflare proxy, create a certificate, add Cloudflare, then switch to webroot.

Hmmmm, but the Apache authenticator in Certbot correctly supports HTTP-01 challenges since the deprecation of the old TLS-SNI-01 method. They can also be valid when HTTP is redirected to HTTPS, although there might be situations in which this doesn’t work.

I think your advice may be correct but it’s still not clear that this should inherently fail to work.

@cmlaplata, si tiene la intención de seguir usando Cloudflare, también puede considerar la opción de utilizar el certificado de origen de Cloudfare, lo que eliminaría la necesidad de un certificado Let’s Encrypt.


So first i need to remove de Lets encrypt Certificate? Oh i feel is so difficult this things.

First of all thanks!! When say maybe a solution can be use Cloudflare integrated solution or Cloudflare origin certificate is this? Image here off cloudflare: https://i.imgur.com/8XjstOB.jpg
I found that. If i configure that my website work again?

Puede ser una buena opción en vez del certificado Let’s Encrypt.

Otra posibilidad, si quiere otra opción, sería actualizar su versión de Certbot (0.31 está bastante desactualizada).

Thanks! I dont know if you answer in spanish or the website translate the answer jajaja.
First i gonna try turn off cloudfare, redirect the dns to Digital Ocean and try to renew certificate. If does not work i gonna try to install the origin server Cloudflare certificate!
