Ipv6 errors when I try to request new ssl via lets encrypt

I’m getting the following error on 2 of my domains (yet I had no trouble issuing SSL certs for my other domains). The server is not configured to use IPv6. And the domains in question also don’t have (to my knowledge) an IPv6 record configured.
Errors were found in your system’s BIND configuration : zone domain.com/IN: NS ‘server.domain.com’ has no address records (A or AAAA), zone domain.net/IN: not loaded due to errors., _default/domain.net/IN: bad zone

One thing that I have noticed though is when I am in the Let’s Encrypt tab it is showing the following “associated domains”:

mydomain.com
www.mydomain.com
mail.domain.com
autoconfig.domain.com
autodiscover.domain.com

Whereas, my other domains only show:

domain.com
www.domain.com
mail.domain.com

I should note that these domains are ones that were hosted elsewhere under in another virtualmin server account and did have the autodiscover and autoconfig subdomains created. I have tried the option: Request certificate for → domains listed, and only putting in mydomain.com but I am still getting the IPv6 error. How can I flush out any errors and ‘stuck’ domains?

Please help! My website has not SSL… and google flagged it.

Hi. It is very strange to troubleshoot your case without knowing anything about your config:)

Did you try disabling IPv6?
Are you able to successfully ping your hostnames for outside?
What “Re-Check Configuration” returns?
Provide LE cert request output.

Help us to help you, provide as much details as you can, but do not list everything you can.

Finally thanks for replay!

Well… I have disabled my ipv6. in Virtualmin…

My website is working…and I can ping it outside.
I had my website in vultr. Then I have made backed up my website from Vultr to a new dedicated server . After restoring the website everything is working fine exept the SSL certificate issue.

You are right when I click on Re-check configurations then I get same error as the one I got when I order Let’s encrypt.

Here is my webstite. cheapseovps.net
the server is pointed to server.cheapseovps.net with the dedicated server IP.

Have I answred all your questions?

Copy & paste the error text.

Here is my network configuration

Here is the error… its same error when I order SSL certificate via lets encrypt.

I did ask to show the error text.

You revealed your IP addresses only. Where is the error text?

This error text.

No… here is it

same error here

I suggest you disabling IPV6 first if you really do not need it.

Here is my hosts configuration

Yes… I have already done that… in virtualmin. have you checked my network settings?

Good. Now, open your virtual server, click on “edit…” and show me this blurring sensitive info.

Aha… you would like to log in or… I dont understasnd right now

You need this info?

Show this. The error above clearly states about IPv6 address configured for your Apache host, but I do not understand where it is…

Hello!

Cant see that!
I run ubuntu 18.4.
I tried to disable the IPv6 via those comandos:
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1

still not working…
