After trying to use not external url, there is still this error in browser console: downloadable font: download failed (font-family: "text-security-disc" style:normal weight:400 stretch:100 src index:2): bad URI or cross-site access not allowed source: http://localhost:4200/text-security-disc-compat.ttf . Also the request to http://localhost:4200/text-security-disc-compat.ttf gets blocked because of cors. I tried to allow cors in rails with the rack-cors gem, but nothing worked..

I have also taken another look, tried different methods to allow cors or set the Access-Control-Allow-Origin header, nothing really worked, I also tried to just change the URL to localhost:3000 since we have the assets loaded there too. This also didn't work
