If you receive either of these error messages:
- "The Application WhatsApp has attempted to open a connection inside the firewall and outside the firewall which is not allowed by your IT policy".
- "Uncaught exception: net.rim.device.api.system.ControlledAccessException".
It is possible that you did not grant proper permissions to WhatsApp or that your settings became corrupted. To fix the problem:
Go into Options > Device.
Select Application Management.
Choose WhatsApp and select Edit Permissions.
Set WhatsApp Permissions to Allow and Save.
After saving the new permissions, reboot your BlackBerry by removing the battery from the device.
If you are still having problems performing the above steps, go to Options > SecurityOptions > Firewall, and select Reset Settings from the menu. Be sure to Save, and then reboot your BlackBerry by removing the battery from it for 30 seconds.
If you are unable to change your permissions or firewall settings, please read this article.
