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:tile.semrdemo.com
I ran this command:certbot certonly (selected option 2, then tile.semrdemo.com, webroot)
It produced this output:
Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
Detail: 188.8.131.52: Invalid response from http://tile.semrdemo.com/.well-known/acme-challenge/nByk39Qakzq02zem-d-uE5DjqHOJUXw3bGuImvRXb70: 404
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.

The version of my client is (e.g. output of
certbot --version or

Note, other 'normal' virtual host sites I was able to get certificates easily. (Thank You).
This virtual host is quite different. Here is the site config in apache's sites-available
