Fail to create certificate

srry -
these are the error messages.
Please read them, Do not attempt to test anything.
If you can assist in understanding this error messages and suggest a solution, then this is the purpose:

acme: Error -> One or more domains had a problem:
[] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: Invalid response from 404, url:
[] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: Invalid response from 404, url:
[] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: Invalid response from 404, url:

It means the Let's Encrypt Servers could not find the HTTP Challenge token or file placed by Certbot. The 404 is an HTTP Not Found.

The method Certbot uses for these tokens/files depends on the actual Certbot command (which you did not show).

As for suggesting a solution, you have not provided enough info about why this request failed when other requests have succeeded to get certs (you even got one cert today).


The error messages are clear.
Do you understand what 404 means?

I requested to stop running tests on my domain. The server is down right now. It's a controlled env. I asked for opinions and suggestions about the output that I sent. I did not ask anyone to run tests against it.

I feel this forum is a waste of time, really.

I don't need you to run nmap. You could've asked me about open ports and I would've told you that.

I have found that sometimes servers give different responses from different Internet locations, and some people find that of value. Sorry for inconveniencing you and wasting your time. :frowning:

Use one of the certificates that @MikeMcQ pointed out has been issued.

That is FALSE!

For most people, it is not. I find that the way people respond on the well meant posts from the volunteers greatly effects how my fellow volunteers will respond. Usually, a grateful, constructive attitude will lead to more helpful posts.

Also note that it's often that someone opening a thread thinks they have it already pinned down, but the problem actually was somewhere else. It's not that black and white. So please keep an open mind.

Now, with regard to your problem: you haven't provided us with enough information I'm afraid. The 404 file not found error can have multiple reasons and we need more info to narrow it down. Please share the answer to the unanswered question in the questionnaire to begin troubleshooting:


Thank you, I appreciate the help of all of you greatly. I apologize for my attitude yesterday, I had a really bad day and I was frustrated.
Thank you all for your good will


Where do we stand today?
Is there still a DNS problem OR an Apache server configuration problem?
[OR both?]
Neither - you've figured it all out and have obtained the desired certs!!!
