Thank you for your comment
But it was useless.
I have the same error.
I could install latest firmware from Flash Tool Lite.
I choose IoT Device ->
Address: 192.168.2.15(Edison ssh connect IP Address)
UserName: My Intel XDK Account UserName
Password: My Intel XDK Account Password
connect -> same error.
I tried Edison whitelist add My PC IPAddress.
(Edison and My PC under the same Wi-Fi router)
xdk-whitelist -add 192.168.xx.xxx(My PC IPAddress)
systemctl enable xdk-daemon
systemctl restart xdk-daemon
But I have the same error.
