Failed authorization procedure. dvwa.lab.net (http-01): urn:ietf:params:acme:error:dns :: DNS problem: SERVFAIL looking up A for dvwa.lab.net
I’m noob for these things so I even don’t know how to modify this DNSSEC thing.
Can you help me?
Because I’m doing this on localhost by giving it a domain name as dvwa.lab.net and I want to use https for it for my intranet not for public or open internet.
Publicly trusted certificates can only be issued for real domain names to people who control them.
Let’s Encrypt doesn’t have any other options.
While you can get certificates for hostnames that aren’t publicly accessible – such as by using DNS validation, or split horizon DNS – you have to use your own domain name.
If you want to use that domain (proven that you aren’t the domain owner) in local network, please use a self-signed certificate.
All public trusted certificates must at least prove domain ownership in order for the certificates being issued. (Or there’s some trouble and a CA will suffer)
