我在新服务器直接用curl构建请求curl -X GET "https://api.mch.weixin.qq.com/v3/certificates?algorithm_type=RSA" -H "xxxxxxxxxxx"，就能请求成功并且也通过了，使用代码的sdk构建的config就报请求失败。无语了，目前确定的是就是这里发送网络请求失败，还有个疑惑，为什么会发送请求会失败这个地址：Failed to connect to api.mch.weixin.qq.com/2408:8711:10:10:0:0:0:a5:443，求大神解答~

@Bean
public Config wxPayConfig() {
    try {
        log.info("wxPayConfig init");
        return new RSAAutoCertificateConfig.Builder()
                .merchantId(Wechat.MCH_ID)
                .privateKey(readPrivateKey(Wechat.MCH_PRIVATE_KEY_PATH))
                .merchantSerialNumber(Wechat.MCH_SERIAL_NO)
                .apiV3Key(Wechat.APIV3_KEY)
                .build();
    } catch (Exception e) {
        log.error("Failed wxPayConfig build.", e);
        throw new RuntimeException("Failed wxPayConfig build.", e);
    }
}
