Disconnected: No supported authentication methods available (server sent: publickey)
I reinstall Winscp and Putty, try again but error still there.
I'm try to login to my server using Putty directly (not through Winscp) so everything OK, nothing wrong.
I think Winscp do not forward my private SSH key to Putty. Please help.
// Anotherthing, i download lastest portable Winscp and it version do not have above error.
