Problems Creating Certificate Failing

Help
1

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: lawnveteran.com

I ran this command: sudo certbot --nginx -d lawnveteran.com -d www.lawnveteran.com

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx

Failed authorization procedure. lawnveteran.com (http-01): urn:ietf:params:acme:error:dns :: No valid IP addresses found for lawnveteran.com

IMPORTANT NOTES:

My web server is (include version): Digital Ocean

The operating system my web server runs on is (include version): Ubuntu 18.04

My hosting provider, if applicable, is: Digital Ocean

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No.

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.31.0

There is no DNS IP for the base name:

Name: lawnveteran.com
[empty]

Name: www.lawnveteran.com
Addresses: 2604:a880:800:c1::18d:4001
142.93.181.82

But why does it say that if I can access my website correctly.

4

Because browsers are too smart and add www by themselves. Copy the addresses to the base domain too.

You currently have:

www IN A    142.93.181.82
www IN AAAA 2604:a880:800:c1::18d:4001

You should have:

@   IN A    142.93.181.82
@   IN AAAA 2604:a880:800:c1::18d:4001
www IN A    142.93.181.82
www IN AAAA 2604:a880:800:c1::18d:4001

Does it takes time to reflect the change? I added @ in A and @ in AAA in my Digital Ocean.

Few seconds to few minutes

Thanks you the best!!! How do you know all this? I can know all programming languages but if I don’t know how to configure a server it makes no sense.

Sometimes you need to read the source documents: https://en.wikipedia.org/wiki/Domain_Name_System#RFC_documents

Thanks for sharing. Hopefully someone else in here will find this very useful.

But now i try to do a re run for renewal to see if it will renew and i get the same error as before.

11

how you get this information?

12

show me the whole log.

14

now it worked. so interesting. Where can i get

@   IN A    142.93.181.82
@   IN AAAA 2604:a880:800:c1::18d:4001
www IN A    142.93.181.82
www IN AAAA 2604:a880:800:c1::18d:4001
15

where can you get your dns records?

you can type whatever you want in there, as long as it points to actual servers. @ just means “the top domain in this zone.”

17

Yeah but where can I get the information itself for my DNS

Like this:

@   IN A    142.93.181.82
@   IN AAAA 2604:a880:800:c1::18d:4001
www IN A    142.93.181.82
www IN AAAA 2604:a880:800:c1::18d:4001
18

I mean you got it from somewhere.

19

I copied it from your own posts. You can also get it from the dns servers using dig or nslookup.

20

No, I didn’t post that.

21

You did, just not in that format :wink:

22

Ahh I see dig or dnslookup! Man you are too good!
