Solution: The above problem is because of proxy settings. So we have to do the following.
1. Right Click on the network tray icon near the clock
2. Open Network and Sharing Centre
4. Choose connection tab in the newly opened window.
5. Select LAN settings
6. Select Automatically detect settings
7. Apply –> OK
Close all the windows. Open the browser and go to the login page of the IIBF’s website and try to login. If you still face problems, open your browser and go to settings page and deselect/de activate proxy. So now you can log in.
