What to do if StreamLocator won't start
With Fire TV 2nd Gen you may have issues turning StreamLocator on. StreamLocator may attempt to connect but it will appear to fail.
The most common reason for this is a problem with Amazon VPN permissions. Amazon Fire TV requires you to allow permissions for VPN connections. Sometimes Amazon fails to show the VPN permissions popup which will prevent StreamLocator from starting.
The simple solution is to Restart your Fire TV which should trigger the VPN permission notification when you open the StreamLocator App again.
Restart your Fire TV by following these steps:
Step 1:
Hover over the "settings" tab and select My Fire TV 
Step 2:
Scroll down and select "Restart"
Step 3:
A popup will show up, select "Restart"
Step 4:
Open up the StreamLocator App and turn on Streaming by selecting the button below. Select "allow" when the VPN permission popup appears.
If this doesn't work, please uninstall and reinstall StreamLocator VPN
