Question Lets encrypt for a server

[UHolthausen]

Hello

I'm trying to secure a server with Letsencrypt.
Unfortunately Letsencrypt reports an error:

Details
Invalid response from https://acme-v01.api.letsencrypt.org/acme/authz/q1ehcUwLDmbf9DlvM4Sozh0ICZLNVClDixiE9unp6jk.
Details:
Type: urn:acme:error:connection
Status: 400
Detail: dns :: DNS problem: NXDOMAIN looking up A for server.xxx-xxxxxxxx.de

but I have this NX record in the DNS.
Somehow I have a board in front of my head

Note: use the nameservers of the hoster, no own nameservers.

The error 'NXDOMAIN' means 'Non Existent Domain' - the Let's Encrypt network cannot resolve your domain / hostname, Plesk have an article about this issue:

I am not sure that post is related to the issue you are having.

You could try running your hostname (server.xxx-xxxxxxxx.de) through a DNS tool such as MXToolbox which may reveal the issue:

...or private message me your domain name and I will take a look!
