Dear Gokulakrishnan Techt,
Thanks for your inquiry in Quectel Froum.
For your issue, it is better to provide the whole debug log which contained the error information, and whether you have try another URL to have a try ? In order to confirm your issue, it is better to check the URL, then confirm the network status is OK, and use the example that included in SDK package. Thanks!
