Can't refresh anymore on WD Mycloud

I have a WD Mycloud drive since several months now and everything was working fine.
But since yesterday, Infuse can’t refresh my library.
I tried with another drive that worked before and it’s working. But the mycloud can’t be loaded and that’s very annoying because all my new content is in it and it’s faster with this WD.
Did anyone has a clue ?
Thanks a lot
