Error at "request Certificate"

Hello, i need some help. Because i have only installed the server new. Because we want to user LAMP instead of Nginx. Under Nginx and virtualmin we have received a certificate.

My domain is: meatec-intranet.de

I ran this command: Virtualmin GUI (LAMP) to request a certificate

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log

Hi @acer2k

checking your domain you have ipv4 and ipv6 - see https://check-your-website.server-daten.de/?q=meatec-intranet.de

Host Type IP-Address is auth. ∑ Queries ∑ Timeout
meatec-intranet.de A 45.157.176.40 Karlsruhe/Baden-Württemberg/Germany (DE) - netcup GmbH Hostname: v220201075330129175.powersrv.de yes 1 0

But your ipv6 sends different content.

Looks like your Virtualmin doesn't answer with ipv6.

So

  • remove the ipv6 (or, better)
  • change your Virtualmin, so ipv6 works

Checking your domain Letsencrypt prefers ipv6, so that's critical.

Thx Juergen,
i have now removed the ipv6 out from the DNS an i will test this, after the reset of my rate limit :slight_smile:

You didn't create certificates, so it's only the failed validation limit - one hour.
