Unable to connect to server in 4G LTE network in iPhone5

Hi Folks,

I am using cocos2d-1.0.1-x-0.13.0 and libcurl for making http calls in a project.

Everything works fine but except on iPhone 5 with 4G LTE network. Whenever switch to LTE network, I am not able to connect to server. but it works fine on wifi on same device.

Can someone here guide me on this issue.

Thanks in advance.
