无法从本地主机访问 API，但可以从外部访问

Question

我编写了一个包含 WooCommerce API 的快速 API。

当我从我的电脑开发应用程序时，我没有遇到任何问题。但是知道我把它放在一个带有乘客的 Apache 服务器上，它位于像 api.example.com 这样的子域上，它会返回这个错误：

{
  "message": "certificate has expired",
  "name": "Error",
  "stack": "Error: certificate has expired\n    at TLSSocket.<anonymous> (_tls_wrap.js:1105:38)\n    at emitNone (events.js:106:13)\n    at TLSSocket.emit (events.js:208:7)\n    at TLSSocket._finishInit (_tls_wrap.js:639:8)\n    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:469:38)",
  "config": {
    "url": "https://example.com/wp-json/wc/v3/orders",
    "method": "get",
    "params": {
      "per_page": 100
    },
    "headers": {
      "Accept": "application/json",
      "User-Agent": "WooCommerce REST API - JS Client/1.0.1"
    },
    "auth": {
      "username": "_",
      "password": "_"
    },
    "transformRequest": [
      null
    ],
    "transformResponse": [
      null
    ],
    "timeout": 0,
    "responseType": "json",
    "xsrfCookieName": "XSRF-TOKEN",
    "xsrfHeaderName": "X-XSRF-TOKEN",
    "maxContentLength": -1,
    "responseEncoding": "utf8"
  },
  "code": "CERT_HAS_EXPIRED"
}

当我直接从服务器卷曲 API 时，它返回给我：

curl https://example.com/wp-json/wc/v3/orders/400 -u consumer_key:consumer_secret
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

curl: (60) SSL certificate problem: self signed certificate in certificate chain

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

如果之前没有告诉我，这个错误怎么会是真的？

这是我的域 SSL 配置。
