Error listing directory "/"

Hello.

When I want connect my computer to my Wii U. It waits for said me "Error listing directory "/" ".
I have got this problem before.
With the new version of WinSCP, it works. For 2 days.
Now I have this again.
Do you know how to correct this ?

Thanks you for the help.

What protocol are you using? Can you connect with any other client using the same protocol?

I use the FTP protocol because I need te connect to port 21 for access to my Wii U game files with WinSCP. And nope.

So why do you think the problem has anything to do with WinSCP?
What did you do previously to fix the problem?
