Issue is that cross site access not allowed source cdn.rgb-profiles.xyz/font-awesome/fonts... We had a similar issue. Despite the fact that we loaded font awesome fonts from Droplet and not Spaces we got this error. That was due to relative link trying to load font from Spaces CDN. When we did set CORS at Spaces to allow access origin * we got a 404. We did however not want to use allow access origin all so we fixed the url and loaded from Droplet.

If you can set origin to specific location at Spaces CORS settings and do this for at least GET (PUT and POST probably not needed) that should get things working again. At least when fonts are on Spaces. And setting specific source (your website) will make it specific enough and thereby not inherently insecure.
