DNS problem: SERVFAIL looking up CAA for www.188589.com

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: 188589.com 656685.com www.188589.com www.656685.com

I ran this command: certbot certonly --break-my-certs --force-renewal --agree-tos --manual-public-ip-logging-ok --no-eff-email
–manual --preferred-challenges http -m "xxxxxx@gmail.com"
-d “188589.com 656685.com www.188589.com www.656685.com
–manual-auth-hook “$Folder/SSL_auth_http.sh” --manual-cleanup-hook “$Folder/SSL_clean_http.sh”

It produced this output: Get SSL cert for 188589.com, 656685.com, www.188589.com, www.656685.com

All setting are same and there are no CAA record on those 4 Domains.
Why only www.188589.com got CAA issue?

Hi @glorysky222

the first nameserver has a timeout:

nslookup www.188589.com.
DNS request timed out.
timeout was 2 seconds.
Name: bg99.08cdn.com
Addresses: 116.213.43.91
47.90.101.122
Aliases: www.188589.com
ub2610.tudouser.com

One timeout -> complete fail. I don’t know why there is no second try.
