My hosting provider, if applicable, is: google domains

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): yes

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

I’m already checked records of my domain.
Also I waited full time to verify the record is deployed :frowning:


Did you remove that record after challenge failure?
I can’t really find that record via dig or nslookup or anything similiar.

Thank you

The check I ran returned "empty".
nslookup -q=txt

No, I did not remove the record.
I waited about 5 minutes.

In my google domain services.
Is there any other ways to check the acme-challenge records?

Is that record still present?
Since we really can't find it.

You could use something like , or Network Tools: DNS,IP,Email to check your TXT records.

Thank you

Also, can you confirm that you've added the TXT record onto

Thank you
