Javascript amazon CDN问题，JS和字体文件错误502

我即将使用amazon cloud front为我的网站设置cdn

它可以很好地处理图片，但会在字体和js文件上抛出错误。规则设置完全相同，我不知道为什么会出现此错误：

Font from origin 'foo' has been blocked from loading by Cross-Origin 
Resource Sharing policy. No 'Access-Control-Allow-Origin' header is 
present on the requested resource. Origin 'bar' is therefore not 
allowed access. The response had HTTP status code 502.

我阅读了有关Access Control Allow Origin标头的信息，并将其添加到.htaccess中，如下所示，但无效：

Header add Access-Control-Allow-Origin "*"

（也尝试了域名，没有区别

任何暗示都将受到高度赞赏
