getting "Inputstream is closed" when using sftp deployment

Hi,

I have a linux system running my web server and I try to configure Webstorm (running on Max OSX yosemite) to deploy my stuff to it and I keep getting that error "inputstream is closed"

I can use "scp" and "ssh" to copy files and connect to the server without any problems but the stfp deployment features in webstorm simply does not work.

I look at the logs and it does not help more

"...
Caused by: java.io.IOException: inputstream is closed
      at com.jcraft.jsch.ChannelSftp.fill(ChannelSftp.java:2884)
      at com.jcraft.jsch.ChannelSftp.header(ChannelSftp.java:2908)
      at com.jcraft.jsch.ChannelSftp.start(ChannelSftp.java:262)
     ... 29 more"

Anyone can help me ?
