根因分析

CloudFront 无法与自定义源建立 SSL/TLS 连接，因为源的 SSL 证书无效、过期、自签名或与源域名不匹配。

English

CloudFront cannot establish an SSL/TLS connection to the custom origin because the origin's SSL certificate is invalid, expired, self-signed, or does not match the origin domain name.

官方文档

解决方案

  1. Ensure the origin's SSL certificate is issued by a trusted CA (e.g., Let's Encrypt, DigiCert) and matches the origin domain. Use `openssl s_client -connect origin.example.com:443 -servername origin.example.com` to test the handshake.
  2. If the origin uses a self-signed certificate, upload the certificate to ACM (Certificate Manager) and attach it to the CloudFront distribution: `aws acm import-certificate --certificate file://cert.pem --private-key file://privkey.pem`.
  3. Configure CloudFront to use the 'Origin Domain Name' that matches the certificate's Common Name (CN) or Subject Alternative Name (SAN).

无效尝试

常见但无效的做法:

  1. 70% 失败

    The SSL handshake still fails because the certificate issue remains; CloudFront requires a valid certificate.

  2. 40% 失败

    This is a workaround but compromises security; it may not be allowed if the origin requires HTTPS.

  3. 85% 失败

    The certificate issue is persistent; restarting does not fix the SSL configuration.
