Why does the mydlink Mobile App connection work on Wi Fi but not on my 3G or 4G Connection

This could be due to the following reasons:

1. Your routers uPnP feature is Disabled.

2. Your Router is not getting a proper public IP address from your Internet Service Provider. *This is common if your ISP modem is actually a Modem/router combo"

3. Your Phone reception is weak

4. Your phone provider has a firewall which is blocking the mydlink (Stunt/Relay) connection.
