用Application Loader上传，一直显示

正在将项目包上传到App Store...

好无辜啊，上传3天了，一直卡在上传中，郁闷

• The session's status is FAILED and the error description is 'failed to open ssh session. (16)'

• An error occurred while uploading the file xxx.ipa.
• An exception has occurred: Broken pipe
• Failed to upload file: xxx.ipa
• Communication error. Please use diagnostic mode to check connectivity. You need to have outbound access to TCP port 443.
• An exception has occurred: Operation timed out

有报错还好一点了，不会一直卡住，哎，不知道什么时候才能上传好呢，有高手解答一下吗？ 如果上传，用了vpn也还是不行，高手们是怎么上传到app store的呢？
