我用的是ubuntu 16，我下载并安装了最新版本的android-studio（文件android-studio-ide-181.5056338-linux.zip）。
我在一个公司代理后面运行android工作室。我解压缩文件，启动studio.sh，并通过以下链接配置代理：https://developer.android.com/studio/intro/studio-config#proxy和https://www.jetbrains.com/help/idea/2018.1/settings-http-proxy.html
注意：我还配置了代理身份验证（用户名和密码），如下图所示：

当我检查连接时，如果我使用一些不安全的URL（例如http://www.google.it）都工作得相当不错;可以结账。如果我使用安全URL（例如https://www.google.it）我得到一个407错误（需要身份验证），如下图所示

然后我保存了设置并关闭了IDE。注意我还没有创建项目...我刚刚安装了IDE。
现在，每次在idea.log中启动IDE时，我都会看到以下错误：

所以看起来我的代理设置没有被更新阶段使用。注意我也尝试使用不安全的连接，但错误仍然存在。
我能解决这个问题吗？
