Không thể kết nối với VPS của tôi trước khi khởi động lại máy Mac của tôi

Tôi sử dụng mạng LAN trong văn phòng của chúng tôi. Tôi có thể kết nối với máy chủ VPS của mình bình thường.

Nhưng khi tôi trở về nhà, (với Macbook đang ngủ), hãy sử dụng mạng WLAN, tôi không thể kết nối cùng một Máy chủ.

Không tip cho tôi mật khẩu đầu vào. Chỉ nói với tôi ""

Tôi đã cố gắng xóa bộ nhớ cache về SSH: remove ~ / .ssh / know_hosts; ssh-add -D (xóa tất cả danh tính).
Không có công trình.

Nhưng sau khi khởi động lại máy Mac của tôi, mọi thứ đều ổn.

(After a long waitting... )

Connection closed by 199.119.ip.ip

Khi tôi trở lại văn phòng của mình, nó sẽ như thế này:
