java 图形API -关闭通道异常

我收到ClosedChannelException错误，而发送邮件使用图API。我知道连接参数是正确的，因为它工作正常，当我尝试通过 Postman 。而且我的旧代码与图API 1.6.0工作正常。我试图升级到5.45.0。有人知道什么问题可能是什么吗？代码看起来正确的我。所以我也尝试改变依赖的jar版本，但是到目前为止没有任何效果。
我将以下代码与令牌凭证身份验证提供程序一起使用。https://github.com/microsoftgraph/microsoft-graph-docs/blob/main/api-reference/v1.0/includes/snippets/java/user-sendmail-with-attachment-java-snippets.md
所用版本：微软-图表-5.45.0天青-鉴别-1.7.3React器-芯-3.5.2React器-网状物-1.1.2网状物-全部-4.1.87.最终

"2022年2月3日"更新：我尝试了下面的代码来检查令牌部分是否正常工作，发现它也抛出了同样的错误。

IAuthenticationProvider authProvider = new TokenCredentialAuthProvider(scopes, clientSecretCredential);
            java.net.URL url = new java.net.URL("https://graph.microsoft.com/v1.0/users");  
            String token = authProvider.getAuthorizationTokenAsync(url).get();
