"I have CoreFTP server on a box that has been working ok up to today. All of a sudden, when I try to connect from my Linux box to my CoreFTP windows box, I get the following message:
Received disconnect from XXX.XX.XX.XXX: 2: key check failed
Couldn't read packet: Connection reset by peer "
I have more or less the same problem. Find error below
