Simple HTML page has Error 500 on mobile devices but not on desktop

Ok, so I have a VERY SIMPLE html page on a website so people can access a couple files.

The problem is that this page loads fine from a desktop computer using a standard browser, but when attempting to view it on a mobile device, I get ERROR 500. So, is there some simple header info I need to add to the file to get it to display on a mobile device?

Here's the URL:
