Me podrían ayudar con los siguientes errores en el explorador:

GET http://localhost:3000/ 404 (Not Found) localhost/:1 Refused to load the image 'http://localhost:3000/favicon.ico' because it violates the following Content Security Policy directive: "default-src 'none'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.

Los obtengo después de probar: node server.js min 4:15
