Refused to load the font 'data:font/woff.....'it violates the following Content Security Policy directive: "default-src 'self'". Note that 'font-src'
Solution 1:
For me it was because of the Chrome extension 'Grammarly'. After disabling that, I did not get the error.
Solution 2:
To fix this specific error, CSP should include this:
font-src 'self' data:;
So, index.html meta should read:
<meta http-equiv="Content-Security-Policy" content="font-src 'self' data:; img-src 'self' data:; default-src 'self' http://121.0.0:3000/">
