Question

如果系统通过代理连接到Internet，则不会进行自动更新。我可以通过Chrome浏览器访问http://gt-test-asca-release.xxx/GreytipAstra_windows_3_0_1.exe（我在Chrome浏览器中配置了代理），但使用install4j构建的应用无法自动更新。我在任务管理器中看到bgupdater.exe正在运行。请帮助。

注意：如果计算机直接连接到没有代理的互联网，则会成功进行自动更新。

编辑3： 我在下面的代码中添加了-Djava.net.useSystemProxies=true但是获得了与 EDIT 2 相同的日志。以下是代码段：

关于系统代理和代理凭据，我在下面添加了它的快照：
