DNS problem: NXDOMAIN looking up TXT


My domain is:


I ran this command:

certbot certonly -d *.mattish.com --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory

It produced this output:

Hi @SneakyTurt1e

I see, you have already checked your domain via https://check-your-website.server-daten.de/?q=mattshi.com

This looks good.

TXT - Entries

Domainname TXT Entry Status ∑ Queries ∑ Timeout
mattshi.com ok 1 0

_acme-challenge.mattshi.com oA3rdv-T9WcSGlXBDW5_R4fTMiEYvPqroImxao5uyNU looks good 1 0

_acme-challenge.www.mattshi.com.www.mattshi.com Name Error - The domain name does not exist 1 0

But therre

you are checking mattish.com without an i. There is no txt entry defined.

So it looks like a typo.


Thank you very much for your help, I made a very stupid mistake :rofl:. Please close it.


Typos happens. And typos are first always invisible.

I know that! :wink:
