Cannot run the example code...network issue

[shantanudasgupta]

Hi,
I am trying the example code given as main.py. But it is terminating at the line
socket.getaddrinfo('micropython.org',80)[0][-1] with the following:
(1, 'Connected')
IP: 10.171.145.161
Connected !
Traceback (most recent call last):
File "", line 98, in
IndexError: list index out of range
Obviously there is a network connection error through PPPOS protocol.
I have a working SIM card with internet connection & the APN name setting also seems to be O.K
The network LED is flashing @ 1 sec and @3 sec alternately.
The responses:
(14576385) [PPPOS CLIENT]: status_cb: Connected
I (14576385) [PPPOS CLIENT]: ipaddr = 10.171.144.241
I (14576386) [PPPOS CLIENT]: gateway = 192.168.254.254
I (14576392) [PPPOS CLIENT]: netmask = 255.255.255.255
I (14576398) [PPPOS CLIENT]: ip6addr = ::
Any pointers?
