Generate the url of a document without the "Web server hostname"

Hello,
I tried several ways but I am not able to generate a URL through the custom command function "Generate HTTP URL" without the "Web server hostname" in it.

I would like to have a URL like this: https://www.mywebsite.com/my-file.pdf
However I get the following one: https://ftp.hostname.com/www.mywebsite.com/my-file.pdf

I tried filling in the field "Web server hostname override", however I don't know how to just remove the "Web server hostname" so that the link works correctly online.

Thank you very much for the help.
This app is the best I found on internet.

Putting www.mywebsite.com into "Web server hostname override" should do.

If it does not work, we need more details. A screenshot of the extension configuration would help, as well as an example of a file path, you are generating the URL for.
