Why we have been spcified zero node, the alpha node still try to connect to own's 5080 port?

of course Yes, in my first pic bottom, and also used --bindall flag and whitelist flag. all the firewall has been closed.
i have looked source code, seems like the grpc connect went wrong, i don’t known why the zero instance and the alpha instance can only in the same machine.
machine A run zero instance, it’s ip is 192.168.3.2, start command is dgraph zero --bindall=true --my 192.168.3.2:5080 --raft idx=1
machine B run alpha instance, it’s ip is 192.168.3.4, my alpha start command is: dgraph alpha --bindall=true --zero=192.168.3.2:5080 -v 5 --my=192.168.3.4:7080 --security whitelist=192.168.3.1/16.
the more clear log is:
