尝试上传已通过＆＃39;验证的二进制文件＆＃39;我明白了：
Communications error. Please use diagnostic mode to check connectivity. You need to have outbound access to TCP port 443

尽管在各种类似的SO线程中尝试了所有建议，但我仍然遇到此问题。运行App Loader 2.9.1; Java版本7 build 1.7.0。优胜美地贝塔4; Xcode 5.1.1。还尝试了Java控制面板常规/网络设置中的所有设置。所有防火墙端口都为出站流量打开。
任何新的/进一步的建议赞赏...
