I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Thank you. I tried to reproduce the issue with the debug module, but I could not. It seems this issue doesn't happen on the debug module...

This was first reconnect attempt after server reboot. There might be sshd issues.

Uh... You should put in a clearly labeled button or menu item for displaying the session log. I couldn't find it right now in a hurry o.o
