I have next error when try to create certificate on CentOS 8(WepApp is nginx) by command:
certbot certonly --authenticator manual -d testnklab.com
And make it available on your web server at this URL:
Press Enter to Continue
Certbot failed to authenticate some domains (authenticator: manual). The Certificate Authority reported these problems:
Detail: DNS problem: NXDOMAIN looking up A for testnklab.com - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for testnklab.com - check that a DNS record exists for this domain
Hint: The Certificate Authority failed to verify the manually created challenge files. Ensure that you created these in the correct location.
Some challenges have failed.
- How to fix the error?
