Embedding Fonts into HTML Exports (URL of CSS file not working anymore)

Hi,

I used to embed fonts in Axure RP by simply linking to the CSS file here https://experience.sap.com/files/prototypes/public/fonts/all_fonts.css (as in the screenshot below from Fiori Guidelines) but the URL of CSS file is not working anymore.

Has it been moved elsewhere?

Could you please help?

Thank you.
