DMVPN - Ping fails on LAN to LAN

Hi Experts - Seeking your help to understand why I am not able to ping the HUB LAN IP address from Spoke LAN IP address in a DMVPN setup. It is a new installation I am trying to achieve.

 

1. Ping successful when doing from spoke to Hub Tunnel IP (ping <hub-Tunnel IP address>)

2. Ping fails when doing from spoke to Hub Tunnel IP using source Interface as LAN IP add (ping <hub-Tunnel IP address> source <fa 0/0)

3. Ping fails when doing from spoke to Hub fa 0/0  using source Interface as LAN IP add (ping <hub-Tunnel IP address> source <fa 0/0)

 

What is the general reason for this. The output from Router below. Can you help me please. Thanks in advance

I noted when I am configuring

I noted when I am configuring the spoke LAN IP address statically in NHRP, I am able to ping from Spoke LAN to Hub LAN.

ip nhrp map <Spoke LAN IP address> <Spoke Tunnel IP address>

 

But how to make it using Dynamically learn?
