How do allow fontawesome as a style-src in my Content-Security-Policy?

Telarian asked:

I’m trying to set my Content-Security-Policy header in .htaccess.

I’ve already tried a variation of the answer to this post but it doesnt work. All my fontawesome icons are broken.

Header always set Content-Security-Policy: "default-src 'self'; style-src  *"

I’ve also tried using *

I’ve tried setting it with a <meta> tag in my site <head> as well but got the same result.

When using an .htaccess validator I receive the error: “Fatal: Header has too many arguments”

I’m currently receiving this error for this header in particular:

Header set Content-Security-Policy: default-src 'self'; script-src 'self' * *; style-src 'self' * *; img-src 'self'; font-src 'self' *.fontawesome *; connect-src *; media-src *; object-src *; child-src *; frame-src *; worker-src *; frame-ancestors *; form-action *; upgrade-insecure-requests; block-all-mixed-content; referrer no-referrer-when-downgrade

What am I doing wrong?

My answer:

The header value must be quoted if it is meant to contain whitespace.

Your first example properly quotes the value, but your second example does not.
