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](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: [edupecsoftware.com/](http://edupecsoftware.com/) I ran this command: sudo certbot certonly --webroot It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log Please enter the domain name(s) you would like on your certificate (comma and/or space separated) (Enter 'c' to cancel): [edupecsoftware.com](http://edupecsoftware.com) [www.edupecsoftware.com](http://www.edupecsoftware.com) Requesting a certificate for [edupecsoftware.com](http://edupecsoftware.com) and [www.edupecsoftware.com](http://www.edupecsoftware.com) Input the webroot for [edupecsoftware.com](http://edupecsoftware.com): (Enter 'c' to cancel): /var/www/html Select the webroot for [www.edupecsoftware.com](http://www.edupecsoftware.com): * * * 1: Enter a new webroot 2: /var/www/html * * * Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2 Certbot failed to authenticate some domains (authenticator: webroot).

Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded from the internet. Some challenges have failed.

Currently, there's a working website on HTTPS, just with a self-signed certificate. Let's Debug gives the "All OK" result now ([Let's Debug](https://letsdebug.net/edupecsoftware.com/2389508)). If you try again, it _should_ succeed. (Or a new/different problem occurs..) ---
