Why i can't connect to scanner

Hello,

I’ve checked previous posts and i didn’t found any real help about this problem so i’m opening a new post about this subject.

When i want to scan a host i have this issue : “Could not connect to Scanner”.

Why ? I’m completely lost.

Thank you for your help,

DSI_agglo.
