Hi Nayan,
Sorry for the late reply.
Check if proxy connection is enabled. If yes, then disable the proxy connection and check the status.
Follow the steps to disable proxy:
a. Open Internet Explorer.
b. Click Tools and then click Internet Options.
c. Click on the Connections tab.
d. Click on the LAN Settings button.
e. Then uncheck the option Use a proxy server for your LAN.
f. Click Apply.
If that does not help, Microsoft has come up with a little tool. You can download the Microsoft Account Troublefooter from here:
Hope this helps.
