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”
