我不再能够通过git ftp通过ssh连接到我的sftp服务器。我现在收到以下错误：
Failure establishing ssh session
我最后一次成功推送是在2018年5月14日。
我目前正在使用BitBucket管道。我的YML文件如下所示：
image: php:7.0.27
pipelines:
default:
- step:
script:
- apt-get update
- apt-get -qq install git-ftp
- git ftp push --user $SFTP_username --passwd $SFTP_password --verbose sftp://[domain]/.../
据我所知，没有任何变化（变量，主机，路径等）。
git-ftp或BitBucket管道有什么变化吗？
