I can't see dashboard screen

[hasan_kenar]

I want to try localhost:8080 and enter my username admin and password secret in my /etc/sensu/config.json but dashboard screen is not open. I got the same frame again and again. What’s problem?

That’s content of my config file:

    {
      "rabbitmq": {
        "ssl": {
          "private_key_file": "/etc/sensu/ssl/client_key.pem",
          "cert_chain_file": "/etc/sensu/ssl/client_cert.pem"
        },
        "port": 5671,
        "host": "localhost",
        "user": "sensu",
        "password": "mypass",
        "vhost": "/sensu"
      },
      "redis": {
        "host": "localhost",
        "port": 6379
      },
      "api": {
        "host": "localhost",
        "port": 4567
      },
      "dashboard": {
        "host": "localhost",
        "port": 8080,
        "user": "admin",
        "password": "secret"
      },
      "handlers": {
        "default": {
          "type": "pipe",
          "command": "true"
        }
      }
    }
