Without a config snipet it is hard to say, state "Active" means it is trying to establish TCP connection  on Port 179

1) do below 

run ping 192.168.78.4 routing-instance VPN-Internet 

Can you ping neighbour?

2) Is your zone allowed to receive BGP traffic?

show configuration security zones security-zone [ZONE_NAME]

3) Are your AS matching with peer?
