downloadable font: download failed

Hey everybody!

I really like how the Boston Theme looks, very clean and to the point. But unfortunately I have a problem with the font files.

I Installed and activated the Theme here: https://vickymawiva.bplaced.de/wp/

As you can see the header Font is not loading properly, I get this message in my console:

Quellübergreifende (Cross-Origin) Anfrage blockiert: Die Gleiche-Quelle-Regel verbietet das Lesen der externen Ressource auf https://vickymawiva.bplaced.net/wp/wp-content/themes/boston/assets/fonts/Norwester-Regular.woff. (Grund: CORS-Kopfzeile ‘Access-Control-Allow-Origin’ fehlt).
