The debug from the branch shows that they are not getting past the key exchange part of the negotiation. My first suggestion would be to make sure that both peers are using the exact same key. And while you are at it make sure that other parameters also match between peers.

What does debug from the head end show?

I already tried 3 times change the key and all verified the same config for vpn..

debug from hq still does not get. 

But the status in crypto isakmap sa show it will gent qm_idle for a few second and then back to no state.

this config for 
ASA/FPR ?
ISR IOS/XE ?
what is topology here ?

Kindly take simultaneous captures on the public facing interfaces of spoke and the hub, to check if there is bidirectional communication on port 4500

Hello Everyone,

Sorry for late feedback. We already contact cisco support but have a bit problem also. So we suggest to change from Ikev1 to Ikev2. It can help?

But you dont answer me? Make review to my Q

Thanks
