OCSP 与 nginx 无法获取颁发者证书

我在使用 GlobalSign 颁发的证书在 nginx/1.6.2 上设置 OCSP 时遇到了问题。我阅读了许多相关文章，但找到的解决方案都不起作用。当我连接到服务器时，OCSP 不起作用

> openssl s_client -connect cawi.kondeor.at:443 -tls1 -tlsextdebug -status
[...]                                             .

verify return:1

并且 nginx 日志显示以下错误：

[error] 10646#0: OCSP_basic_verify() failed (SSL: error:27069065:OCSP routines:OCSP_basic_verify:certificate verify error:Verify error:unable to get issuer certificate) while requesting certificate status, responder: ocsp2.globalsign.com

我发现的所有其他帖子都与该错误有关，Verify error:unable to get LOCAL issuer certificate该错误已通过修复证书链得到解决。我的证书链似乎没问题，因为openssl ocsp命令有效（但前提是我使用-header "HOST" "ocsp2.globalsign.com"CDN 带来的参数）：

这可能是 Cloudflare 的问题，还是我忽略了什么？任何帮助都非常感谢！

感谢大家的评论！这让我再次仔细查看了证书链，我注意到我没有将根 CA 证书放入文件中root_ca_and_intermediate.pem，而是将中间证书放入了两次。

因此，现在的工作设置是，文件signed_cert_and_intermediate.pem包含网站的实际证书（第一个）和用于签署实际证书的中间证书（第二个）。文件root_ca_and_intermediate.pem包含中间证书（第一个）和用于签署中间证书的根 CA 证书（第二个）。
