Hello, I'm kodama.
I ran a command for generating a renew certificate on Certbot.
However, some domains couldn't generate for the renew certificate by the following DNS error.
== error message ==
DNS problem: SERVFAIL looking up CAA for domain name1 - the domain's nameservers may be malfunctioning.
DNS problem: SERVFAIL looking up TXT for _acme-challenge.domain name2 - the domain's nameservers may be malfunctioning.
Hint: The Certificate Authority failed to verify the DNS TXT records created by the --manual-auth-hook. Ensure that this hook is functioning correctly and that it waits a
sufficient duration of time for DNS propagation. Refer to "certbot --help manual" and the Certbot User Guide.
I could generate other domains for the renew certificate completely on Certbot, but I could not generate just specific 2 domains.
I would like to give me advices for resolving this error.
Thanks a lot for your help.
