我们使用管道建立了从bitbucket到azure app服务部署的持续集成。它一直工作得很好，从本周早些时候开始就没有复制过程。
我们使用ncftpput将文件从bitbucket ftp到azure，下面给出一个样本。
ncftpput -v -u "$FTP_USERNAME" -p "$FTP_PASSWORD" -R $FTP_HOST /site/wwwroot/Views *
它开始复制文件，但在复制了一些文件后，我们收到了这个错误....
Passive mode refused.
ncftpput pdf.png: passive mode failed.
在ncftput中使用-d stdout，示例日志输出...
Cmd: PASV
227: Entering Passive Mode (40,120,124,239,39,110).
Cmd: STOR SuperAccount/CreateAdminUser.cshtml
