CloudFront无法连接到源

Question

我已经通过http正确设置了Cloudfront.它从我的网站(dev.pie.video)获取数据很好.我现在转向https.事情https://dev.pie.video进展顺利,但Cloudfront无法为任何内容提供服务.例如https://dev.pie.video/favicon-96x96.png有效,但https://d1mbpc40mdbs3p.cloudfront.net/favicon-96x96.png失败,状态为502,即使我的Cloudfront分发d1mbpc40mdbs3p指向dev.pie.video.

更多细节如果有用:

• d1mbpc40mdbs3p.cloudfront.net 使用默认的CloudFront证书进行https
• Cloudfront Distribution的起源设置为通过SSL和TLS工作,并使用查看器的协议.

如果这有用,我从云端获取的日志就像

<timestamp> SFO20   924 96.90.217.130   GET d1mbpc40mdbs3p.cloudfront.net   /favicon-96x96.png  502 -   <someInfoOnTheClientBrowser>    2   -   Error   poZyhl63JNGFk8dIIjCluGDm4dxF8EdMZFhjg82NgHGPNqcmx6ArHA==    d1mbpc40mdbs3p.cloudfront.net   https   494 0.002   -   TLSv1.2 ECDHE-RSA-AES128-GCM-SHA256 Error   HTTP/1.1

Answer 1

您的源服务器未正确配置SSL.CloudFront需要有效的配置,并且可能比某些浏览器更严格 - 因此浏览器中的绿色锁定并不一定意味着您的SSL设置已完成并且与所有客户端普遍兼容.

您的证书由"Go Daddy Secure Certificate Authority - G2"签名,这是一个中间证书(不是root用户),并且您的服务器上没有安装该中间证书 - 因此CloudFront报告它"无法"到连接,实际上它更准确地"不愿意"连接,作为安全预防措施,因为它无法验证您的SSL证书的有效性.您应该在Web服务器的日志中将这些视为SSL协商失败.连接本身正在运行,但由于信任问题,CloudFront认为它无效,因此使用起来不安全.

警告

如果源服务器返回过期证书,无效证书或自签名证书,或者原始服务器以错误的顺序返回证书链,CloudFront将删除TCP连接,返回HTTP错误代码502,并将X-Cache标头设置为Error from cloudfront.

http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/SecureConnections.html

将中间证书添加到服务器配置中,您应该进行设置.这应该在您下载时与证书捆绑在一起,但如果没有,可以在这种情况下从您的CA,Go Daddy获取.

这不是Go Daddy证书特有的限制.遵循标准实践的所有CA都使用中间证书来建立信任链回到受信任的根.
