Hi, I  have a question about WiFi TinyShield.
Now I use WiFi TinyShield and tried to run  "ntpTest" which is prepared as a sample sketch of Adafruit CC3000 Library.

the sample sketch (ntp Test) was used by the tutorial of WiFi TinyShield as well.

I run the sample sketch in the same way as the tutorial, but I got the following message from serial monitor.
I could connect to the wifi, however failed to get socket.
Why couldn't the shield get socket ?  Tell me please.

PC: Mac
Arduino: ver 1.6.7
