Do you have internet connection after MAC changed? if not, you need to disconnect and reconnect (wired or wifi). Try to see if you able to go to google or yahoo.
If you have internet connection, check your VPN setting you might set it only allow your real MAC address only.

The question here might be how you are changing your mac address. If you are doing it from the terminal window via command line try instead changing it via the network-manager instead.

1. Right click on the network manager icon(two computers) upper right on screen
2. Select Edit Connections
3. Selet Wired or Wireless
4. If wireless select connection
5. Select Edit
6. Fill in the mac address you want to spoof in the Cloned Mac Addess box
7. Save
