ERR_CRYPTO_CUSTOM_ENGINE_NOT_SUPPORTED
请求了一个 OpenSSL 引擎(例如,通过 clientCertEngine 或 privateKeyEngine TLS 选项),但所使用的 OpenSSL 版本不支持该引擎,这很可能是由于编译时的标志 OPENSSL_NO_ENGINE 所致。
【An OpenSSL engine was requested (for example, through the clientCertEngine or
privateKeyEngine TLS options) that is not supported by the version of OpenSSL
being used, likely due to the compile-time flag OPENSSL_NO_ENGINE.】
