Android Question SMB exception Failed to connect

[ViMeAv ICT]

I have a problem on one pc in a network, giving this SMB error message.
All other pc's have no problem connecting to the app.
The folder is shared, no password required, I can go into the folder from
every other computer etc.

But when I start syncing I get the message : Failed to connect.

Who can help?

Update : Using ANDSMB gives on all other pc's folder info.
On this pc it only shows : [Go up a folder] and no folder names.
