我正在 AlmaLinux 8.8 (Centos) 和 Apache 2.4.56 上运行一个站点。该网站有一个自签名证书。

当我访问该网站时，由于自签名证书，我收到了常见的警告。接受我要继续后，我SSL_ERROR_HANDSHAKE_FAILURE_ALERT在 Firefox 和ERR_BAD_SSL_CLIENT_AUTH_CERTChrome 中收到错误消息。

在同一服务器上，其他站点可以使用 Cloudflare + Let'Encrypt 正常工作。

我对 Apache 虚拟主机文件上的 SSL 配置没有任何疑问。我也仔细检查了证书。

我运行了这个调试工具，openssl s_client -state -debug -showcerts -verify 1 -connect example.com:443
您可以在下面找到输出的摘要。

我提请大家注意提及 Cloudflare 的行SSL3 alert read:fatal:handshake failure和另一行，即使该网站当前未使用 Cloudflare。

请帮忙。

调试工具的输出：
