Using USB camera with RPi 3B 64

Hi all,
I am a newbie to HASSIO, I am having an issue when setting up USB camera (Logitec C270) for using with Motion add-on.
I follow these topics:

to add the Motion add-on from: GitHub - dcmartin/hassio-addons: Home-Assistant add-ons
But I can’t make it works properly, it stuck here:

Publishing configuration to core-mosquitto topic motion/hostname/start
Unable to connect (Lookup error.).

Do you have some suggestions to help me fix it? Thank you very much.

My current configuration:
SW Version:
|Version|150|

HW Configuration:
serial:
/dev/ttyAMA0
input:
UVC Camera (046d:0825)
disk:
/dev/sda1
/dev/sda
gpio:
gpiochip0
gpiochip100
gpiochip128
audio:
0:
name: bcm2835_alsa - bcm2835 ALSA
type: ALSA
devices:
[object Object]
[object Object]
1:
name: USB-Audio - USB Device 0x46d:0x825
type: U0x46d0x825
devices:
[object Object]

+ Motion configuration:

    {
      "log_level": "info",
      "log_motion": 2,
      "devicedb": "motion",
      "name": "hostname",
      "username": "",

      },

      },
      "digits": {
        "url": "",
        "jobid": ""
      },
      "mqtt": {
        "host": "core-mosquitto",
        "port": 1990
      },
      "cameras": [
        {
          "name": "sample",
          "device": "devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2:1.0/input/input0",
          "type": "ps3eye",
          "palette": 15,
          "fov": 75,
          "width": 640,
          "height": 480,
          "fps": 5
        }
      ]
    }

Another configuration are left default. I only update the device path, as found from kernel log:

[ 2.692439] input: UVC Camera (046d:0825) as /devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2:1.0/input/input0

Hi there,
Anyone has the same issue with HA?

Wrong mqtt user/pass?

I don’t know about setting up MQTT, so I leave it default.
