Error when trying to register a certificate

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. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: certbot certonly -d --server "" --standalone

It produced this output: Saving debug log to C:\Certbot\log\letsencrypt.log
Requesting a certificate for

Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:

  • Domain:*
  • Type: incorrectResponse*
  • Detail: DNS look-up of returned no results.*

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

Some challenges have failed.
Ask for help or search for solutions at See the logfile C:\Certbot\log\letsencrypt.log or re-run Certbot with -v for more details.

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

Hi @joost1, and welcome to the LE community forum :slight_smile:

In order to use this command:

You will need to update the DNS zone so that name returns the Internet IP where the site will be hosted.

Right now, it returns nothing/empty string:

[EMPTY reply]

Then you will need to ensure the Internet can reach that IP via HTTP.


Or, use the dns-01 challenge. The certbot-dns-multi plugin for Certbot supports Google Domains since version 4.11.0.


If you're trying to use Google's Certificate Authority, why are you asking for help here?


Because Certbot's error message always directs users here, for any problem, regardless of which CA is being used.

(Which may even be correct, if this is the "certbot support forum" and not just the "Let's Encrypt support forum"? I don't think it's clear whether certbot should change or our community should expect to support other CAs through certbot, which is probably why the messaging is still there in the meantime.)


Don't see why it should be, any more than it should be the support forum for or winacme. ISRG has been quite explicit for a number of years that certbot is a separate project from a separate organization. But that's probably a discussion that belongs in another topic.


I asked about this a few months back and the Certbot team said they discussed this and do not plan changing the referal. I'm not sure if "they" meant just EFF or also ISRG.


While offtopic, my 2 cents:

The Let's Encrypt team has said previously that this Community should not be seen as Let's Encrypt-only nor Certbot-only. This Community (the site) should be there to help to achieve the goals of Let's Encrypt, which is to create a more secure and privacy-respecting web. Regardless of the CA or ACME client used.

Every member of this Community can choose for themselves if they want to help anyone using something else than Certbot or LE. That's their prerogative. But specifically telling people they should not ask for help here due to the fact they're not using LE and/or Certbot is not the way to go.


True; but there is this also
