I tried to generate a SSL cert for my domain: 2-hosts.com with node.js.
I have verified the domain is working with the IP I assigned and also I could access the challenge file without a problem with a browser, but when I used certbot certonly --manual to try to generate the SSL files, it returned the following errors:
“Failed authorization procedure. 2-hosts.com (http-01): urn:ietf:params:acme:error:dns :: DNS problem: SERVFAIL looking up A for 2-hosts.com - the domain’s nameservers may be malfunctioning”
Can anyone help, thanks!
Hi @proson
there is a check of your domain, ~~25 minutes old - https://check-your-website.server-daten.de/?q=2-hosts.com
There you see the problem:

Your name servers are buggy. If there is a query 2-HoStS.cOm, your name servers answers with 2-hosts.com, that's wrong.
Name servers must answer with the exact query.

If you can't change your name servers, that's bad.
