No valid IP addresses found

My domain is: kvault.de

I ran this command: sudo certbot --apache -d kvault.de -d www.kvault.de

It produced this output:

IMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: kvault.de
    Type: connection
    Detail: unknownHost :: No valid IP addresses found for kvault.de

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

Hey Guys, i am new to this webserver and dns things and wanted to get my domain ssl certified. After i tried to do so i produced the error above. My A records are @ A 91.132.145.41 and www A 91.132.145.41 - so i can’t understand why it will not work. Please help me :frowning:

Hi @Kapuzenkopf

looks like you have found a solution.

There are some new certificates, created in the last days ( https://check-your-website.server-daten.de/?q=kvault.de#ct-logs ):

Issuer not before not after Domain names LE-Duplicate next LE
Let's Encrypt Authority X3 2019-07-05 2019-10-03 kvault.de, www.kvault.de - 2 entries duplicate nr. 1
Let's Encrypt Authority X3 2019-07-01 2019-09-29 www.kvault.de - 1 entries duplicate nr. 2
Let's Encrypt Authority X3 2019-06-30 2019-09-28 kvault.de - 1 entries duplicate nr. 3
Let's Encrypt Authority X3 2019-06-30 2019-09-28 www.kvault.de - 1 entries duplicate nr. 1
Let's Encrypt Authority X3 2019-06-30 2019-09-28 kvault.de - 1 entries duplicate nr. 2
Let's Encrypt Authority X3 2019-06-30 2019-09-28 kvault.de - 1 entries duplicate nr. 1

And you use the certificate created today with both domain names:

CN=kvault.de
	05.07.2019
	03.10.2019
expires in 90 days	
kvault.de, www.kvault.de - 2 entries

So both connections are secure.

And you have an ip address :wink:

Host T IP-Address is auth. ∑ Queries ∑ Timeout
