The dmg file is loading as dmg.html, what should I do?

Question

safari

I have a website that I'm working on. This site has a file that you can download. The dmg file is downloaded as dmg.html. This problem is only in safari. The tag containing the link to the file looks something like this:
<a href="filename.dmg" download>скачать</a>
