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: baffleplates.com

I ran this command: sudo certbot certonly --manual --preferred-challenges dns

It produced this output:QTb8m-maSA_4sDwg36_pM1g55qDr6_fEqErPSM0PQ9E

You probably needed to wait longer after setting the record.

I set the TTL to 1/2 hour (the minimum on godaddy DNS management) and waited for more than that before hitting return.

I put some screenshots on the web

TTL doesn’t affect the way Let’s Encrypt looks up records.

I don’t doubt you setup the record the right way, but the only explanation seems to be that GoDaddy took a long time to apply the updates to the nameservers.

Let’s Encrypt can see it now:

  Domain: baffleplates.com
  Type:   unauthorized
  Detail: Incorrect TXT record
  "Ql66D0mB8Bd_hBDcRIuXNlv9ew0TZwt_n4Vkt7EQn6Q" found at
  _acme-challenge.baffleplates.com

Thanks. It has now worked.

It would be useful if certbot output was timestamped.

I have put the correct godaddy DNS image on the Net. mips-erp.com/DNS/DNS2.png

I was confused because I missed the point that “Please deploy a DNS TXT record under the name
_acme-challenge.baffleplates.com” meant named “_acme-challenge” in the DNS record for my domain. Maybe the documentation could make this clear.

Thanks for your help
