Tôi tiếp tục gặp lỗi khi kết nối với đường hầm ssh trên putty

Tôi đang sử dụng phiên bản hiện tại của putty 0,66 và tôi tiếp tục gặp lỗi này

Đã ngắt kết nối: Vi phạm giao thức máy chủ: gói SSH2_MSG_UNIMPLEMENTED không mong muốn

khi tôi cố gắng kết nối với một đường hầm ssh. Đây là nhật ký sự kiện của tôi,

Đối với tôi, mấu chốt là thuật toán trao đổi khóa "Diffie-Hellman" không được triển khai trên máy chủ (xem Kết nối > SSH > KEX ).

Di chuyển thuật toán trao đổi khóa này xuống cuối danh sách và làm cho thuật toán "Diffie-Hellman nhóm 14" lần đầu tiên giải quyết vấn đề cho tôi.

Tôi đã gặp một lỗi tương tự vào 0,63 ... nâng cấp lên 0,67 đã biến mất.
