我已将域名设置为 localhost，将站点 URL 设置为http://localhost/。
我也尝试过http://localhost:80 , http://mydomainname:80（更换主机）
这是我收到的响应错误：

我知道这是一个老问题，OP 可能已经找到了解决方案。我在与该公司合作时也遇到了同样的问题Laravel 社交名流插入。
为了后代，我想在这里发布解决方案。这个问题在这篇文章中得到了解释question：域 graph.facebook.com 解析为某些网络可能未配置为路由的 IPV6 地址。您可以请求 cURL 将 IP 地址解析为其 IPV4 值。设置选项CURLOPT_IPRESOLVE to CURL_IPRESOLVE_V4.
对于社交名流插件，我们必须修改FacebookProvider.php包括附加选项。
Edit
更具体地说，Socialite 使用 GuzzleHttp，我们需要将其作为参数传递给 GuzzleHttp Client 方法：
'curl' => [ CURLOPT_IPRESOLVE => CURL_IPRESOLVE_V4]
