Site to Site VPN between ASA 5510 failed to establish L2L SA

Hello,

I am configuring a site to site VPN with our ASP, we have configured the same paramenters on both sides however, the tunnel is not established. When traffic is sent from the other side the tunnel is established however no traffic passes from my side. When traffic is sent from my side no tunnels gets established and I am getting the following error:

Tunnel Manager has failed to establish an L2L SA.

We are using IKEv1. Can you please take a look at the attached configuration and see what am I doing wrong. The other side is having same kind of tunnels with other customers and everything works fine.
