Certbot not working for me


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: teams.jrmpc.ca

I ran these commands:

sudo certbot certonly --webroot -w /var/www/jrmpc -d teams.jrmpc.ca

sudo certbot certonly --standalone -d teams.jrmpc.ca

It produced this output:

Failed authorization procedure…

The following errors were reported by the server:

Domain: teams.jrmpc.ca
Type: unauthorized
Detail: Invalid response from http://teams.jrmpc.ca/.well-known/acme-challenge/

After several failed attempts to find the correct procedure, I am now locked out with:

Error creating new order :: too many failed authorizations recently…

My web server is (include version):

Web server is internal to my Pharo/Teapot web application.

The operating system my web server runs on is (include version):

Ubuntu Server 18.04 LTS

My hosting provider, if applicable, is:

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



Could you please try to place a test file with dummy content at http://teams.jrmpc.ca/.well-known/acme-challenge/test?

Thank you


What was the rest of the error message?

What’s in your web server’s error log?


Done. The file is fred.html

What’s the full path that you placed the file to? (Start from system root)
You should use that path (remove the test at the end) as your webroot.

Thank you


Do you still have the log file that contains the original error message? “too many failed authorizations recently” hides the reason it was failing before.




Yes, but I can’t upload it. Should I cut and paste the whole thing? It’s very long.



In this case, do you mind to try to issue certificates using this command:
sudo certbot certonly --webroot -w /var/www/.well-known/acme-challenge/ -d teams.jrmpc.ca

Thank you


Pretty much the same error.


The first part of my cut and paste should contain the info you’re looking for.


I’d like to see the rest of this error message:


certbot.errors.FailedChallenges: Failed authorization procedure. teams.jrmpc.ca (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://teams.jrmpc.ca/.well-known/acme-challenge/WJPmcbAzJIX_fm9V9DjyFTycSh-AMLBX9N6xL1zMAcE []: 404


Was /var/www/jrmpc the correct directory?

Are you sure the DNS records are pointing at the correct server?

What did the server’s error logs say?


I’m not sure what you mean by correct directory. My web server is configured to serve files from ‘/var/www’. ‘jrmpc’ is just a subdirectory of that. Do I need to configure file serving from ‘/var/www/jrmpc’?


You just have to have Certbot and your web server use the same directory. That might be “/var/www”. If they’re using different directories, you have to change one of them.

If you wanted to make a file that can be accessed at http://teams.jrmpc.ca/something.html, where would it be? /var/www/something.html? /var/www/jrmpc/something.html? Whatever directory it is, unless the web server has a more complicated configuration, that’s the directory you should use.

What is the web server’s configuration?

What was in the web server’s error log?


Thanks. That worked.


Did you use?:
sudo certbot certonly --webroot -w /var/www/ -d teams.jrmpc.ca
