Basic auth is not working with consul

[sujithvs-dev]

I am passing below arguments to mesos-consul application and it is not getting authenticated with consul. Consul is running behind Nginx proxy layer. Can somebody validate below arguments,

  "args": [
    "--zk=zk://xx.xx.xx.xx:2181,xx.xx.xx.xx:2181,xx.xx.xx.xx:2181/mesos",
    "--log-level=info",
    "--consul",
    "--refresh=5s",
    "--consul-auth=admin:$apr1$0xUM.ti7$dQuRPxHFuNH42LK1iqcMR1"
  ]
