I am using WinSCP 5.9.3.
In uploading (not in background, I get sometimes the error 450 'operation failed'.
Could not get directory listing.
Then WinSCP is waiting for the user to click on 'Again' and then it continues.
So, I can't upload automatically. I always have to be there.
But what is wrong and how can I solve it to upload automatically without clicking 'Again'?
