No data transmitted from arduino Yun to Arduino cloud

For college work, We are tyring to connect our Arduino Yun to Arduino Cloud.
After registered Arduino Cloud, we made thing "fummy"."fummy" has 1 property "earthquake".
"earthquake"'s settings are
Name:earthquake
Type:Character String
Policy:Update regularity
Update Frequency:1

We uploaded sample program to Arduino Yun. This sample program is generated from "code" menu of "fummy" on dashboard.
According to tutorial (Arduino Project Hub),string "oh" and "yeah" may display on dashboard. But no received data displayed.
Why sample program do not work? Is there any solution.

Hi Nakano,
unfortunately, the board is not supported by Arduino Cloud yet, since it does not support https.

To use the Yun board you have to upgrade the firmware to >= 1.6.2
