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. crt.sh | 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:user.kointexx.com
I ran this command: sudo certbot --nginx -d user.kointexx.com
It produced this output:Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for user.kointexx.com
Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:

Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. 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.
