No domains pointing to this server to generate the certificate for.

[truonglee]

I am having problems renewing ssl for domains on the server. They all show No domains pointing to this server to generate the certificate for. Although I have tried checking the dns records are resolved. I have also troubleshooted in this way: https://docs.directadmin.com/webservices/ssl/troubleshooting-letsencrypt.html
is there any way to check the cause from the beginning.

thanks

I see the SSL is working with zerossl.

But you could check some things.

Do you have IPv6 records in the zonefile?

Did you recently changed the DNS because normally this means the DNS is not really propagated correctly.

Did you check the verbose output of:

Let's Debug

Only thing I notice is that the IPv6 of the NS is slow. These NS

ns1.zonedns.vn.         300     IN      AAAA    2401:5f80:2001:5::a
ns2.zonedns.vn.         300     IN      AAAA    2401:5f80:2001:5::a
ns3.zonedns.vn.         300     IN      AAAA    2001:df1:3200::15
ns4.zonedns.vn.         300     IN      AAAA    2001:df1:3200::15

Give a very slow response which might do this but i rather think it is DNS cache
Response resolution time exceeds 2 seconds; some clients may time out.
