web app on load Content Security Policy issue

I m facing this issue on load in my angular app

Refused to load the font ‘http://localhost:8100/Roboto-Regular.ttf’ because it violates the following Content Security Policy directive: “default-src ‘none'”. Note that ‘font-src’ was not explicitly set, so ‘default-src’ is used as a fallback.

localhost/:1 Failed to load resource: the server responded with a status of 404 (Not Found)enter image description here
