Problem with arduino wifi sheild

There is a problem when i was trying to use arduino wifi sheild to communicate with plotly server. I try to plot data using this sheild and the example sketch but there is this error coming up:
… Attempting to connect to WPA network…
… Connected to network
… Attempting to connect to plotly’s REST servers
… Couldn’t connect to plotly’s REST servers… trying again!
… Connected to plotly’s REST servers
… Sending HTTP Post to plotly
… Error initializing stream, aborting. Try again or get in touch with Chris at

I used arduino IDE 1.0.3 as instructed. The plotly wifi library is the newest version. I dont know how to fix it. Please help!
