Installing policy package error

Hello, While I'm trying to install policy package to device, the copy of the package is working fine and then when it enters the state of "Install package to device from commit" the management tunnel goes down for some reason and I'm receiving the following error message "fgfm install run script error(st=2,logsz=150,errno=0 No response from remote" Updating the device, it goes online again but with a Config Status "Conflict" Any advise please?
