The underlying ssh process died

[Pierre-Alain BOURDIL]

Since upgrade to 14.04LTS, i can not backup using neither ssh,nor sftp.
The backup stop and display an alert message :

Erreur interne : The underlying ssh process died

No changes have occured on the local network and i'm able to scp big file from command line without any problems.
I attach the configuration of my backup.

SimpleBackup runs ok when using an extarnal usb disk as destination.

Thank you for using sbackup and reporting this error.

Please provide a logfile or commandline output showing this error. Can you connect to your remote destination in Nautilus? Please also give some information about your system (desktop environment etc.). This would help to track down the issue. Thank you.

Sorry for the delay.

I use ubuntu 14.04 LTS ,with default (unity) wm. But the problem also occurs using sbackup command line (v 0.11.6)
I 'm able to connect using Nautilus

Here is the error message outputed from sbackup command line :
