Hello Praveen,

 

Check the VPN Client Phase 1 algorithms to be consistent with the gateway (or peer) Phase 1 algorithms. Check the IP address range. Check the Local and remote IDs. (You can specify those if there are multiple tunnels between the two) Note: the local ID on one site is the remote ID on the other site and conversely ! Check the PFS to be activated or not on both peers

Also verify the preshared key and try to avoid special characters.
