Host does not exist

Host does not exist - used the same version of WinSCP, same laptop, same VPN, to connect just days ago - it works fine on another laptop - debug log file attached

Can you connect to that host using any other application?

No, not on this laptop – same error with PuTTY – but on another machine (and on this one a few days ago) connecting via WinSCP or PuTTY was no problem – as I said originally, I can connect to the host on another machine using either WinSCP or PuTTY.

What do you get if you do ping hostname?
