Hint to letsdebug.net in error message


when certbot issues this error message,

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address.

you could add a hint to letsdebug.net. Users might find it helpfull because it can detect issues with DNS settings.


Hi @ohlr

thanks. Letsdebug helps in such a case.

But there was an older topic with the same idea. @schoen wrote, that there are a lot of older certbots in use.

So creating a link to a third-party tool may be a problem, if the tool isn't longer available.


But: I think there is another solution. A new topic, pinned under Help with a list of tools with annotations. Closed, with no replies. There are a lot more tools (CT-logs, Ssllabs, Sslmate, a Mozilla Cipher check etc.).

Then it's possible to check such a third-party tool and remove it, if it's not longer active.


I really like that idea!

That’s a good idea too. However, currently certbot also references third-party tools. When succesfully obtaining a certificate it references SSllabs.

The new certificate covers the following domains: ...
You should test your configuration at:

Since letsdebug.net is part of Let’s Encrypt (if I m not mistaken) it’s not even a third party.

Maybe doing both, pinned topic + modified error message is the right way to go.

It is in-fact a third party and not hosted by or built by Let's Encrypt staff :slight_smile:


I think this is a great idea! Are you interested in starting the topic? I would try to pitch in with some links :slight_smile:

Yep, I'm writing something.


Thank you @JuergenAuer, you’re a huge help!


So, there is the list:

Third-party-Tools to check your configuration (closed)

And a second thread, if someone has a question or new ideas:

Third-party-Tools to check your configuration - discussion


@JuergenAuer you didn’t pinned the Third-party-Tools to check your configuration topic, is it voluntarily?

Awesome thread guys. Bunch of tools I didn’t know about.

Perhaps, if you want the thread to make the most impact, certbot should link to the thread in it’s help messages (instead of tools like letsdebug.net, ssllabs.com, etc.) That way help messages point to a “living” document instead of one tool. As certbot ages and ppl maybe using older versions, the help messages still point to new/current list of help tools.

Also maybe can influence other authors to point to same tools thread.

Just a thought.
