Unexpected EOF or 0 bytes from transport stream

and again a big problem, I get the impression that the utility is falling apart. There are 1000 errors in it, if you watch my feedbacks.

I have never had such a mistake, but today it has appeared. There was a simple backup like I always did.

errors
