                                    script-src 'self' 'unsafe-inline' 'unsafe-eval' https://www.google-analytics.com https://www.google.com https://www.gstatic.com/recaptcha/api2/recaptcha__en.js https://ajax.cloudflare.com/cdn-cgi/nexp/cloudflare.min.js;

                                    ";

Refering to caniuse content security policy is only partially supported through the X-Content-Security-Policy header, but not through the standard Content-Security-Policy header. Try using X-Content-Security-Policy header in IE...
