How can I expose GRPC external port 9080 for Dgraph alpha

Sorry @matthewmcneely Iam not given full details, I have added most of them now.

I have started alpha with two systems using below command, and this time I have removed token, IP address 192.168.1.103 and 192.168.1.108.

dgraph alpha --my=192.168.1.103:7080 --zero=192.168.1.103:5080 --bindall=true --security "whitelist=0.0.0.0/0" --expose_trace=0

and

dgraph alpha --my=192.168.1.103:7080 --zero=192.168.1.180:5080 --bindall=true --security "whitelist=0.0.0.0/0" --expose_trace=0

also I tested with single alpha system as well, same error only I got

"errors":[{"message":"resolving login failed because invalid username or password",

zero started using below command
dgraph zero --my=192.168.1.103:5080 --bindall=true --replicas 3 --raft idx=1 --expose_trace=0

I have trying to using /admin endpoint from the same system 192.168.1.103, in this system only alpha running.

below my command for login with admin endpoint .

curl http://localhost:8080/admin --silent --request POST \
  --header "Content-Type: application/graphql" \
  --upload-file login.graphql

cat login.graphql

mutation {
  login(userId: "groot", password: "password") {
    response {
      accessJWT
      refreshJWT
    }
  }
}

below error message getting while try to login using admin, I dont know why it is , but previously I got successful login using localhost , right now Iam getting error.
