Cirrostratusmy active device is (device 1) and my website working fine. when auto faliover happend the active device (device1) become standby , the traffic goes to the active device ( device 2) but my website does not work . it is display blank page only. when i enforce device 2 to becaome standby and device 1 become the active, my website works well.
so what i have to check in this case? note that both device are in sync.

Three things I would check.
1. Do a tcpdump on the BIG-IP device 2. Check what is going on.
2. Did you configure MAC masquerade? If MAC masquerade doesn't mean anything to you - start from here: K15858: How BIG-IP utilizes gratuitous ARP
3. Are ASM policies synced in your device group? Read this: K12200102: Enabling Application Security Synchronization on a device group
