Jetson Nano connection with MQTT server

[NSL-Wx]

After I got the server set up on my local machine, I want use Jetson Nano to run following command:

Run with MQTT_BROKER_IP, MQTT_DEVICE_NAME, and MASKCAM_DEVICE_ADDRESS

sudo docker run --runtime nvidia --privileged --rm -it --env MQTT_BROKER_IP= --env MQTT_DEVICE_NAME=my-jetson-1 --env MASKCAM_DEVICE_ADDRESS= -p 1883:1883 -p 8080:8080 -p 8554:8554 maskcam/maskcam-beta
but I can't establish MQTT connection from the device to the server, than I use Jetson Nano try following command:
ping
I found I can't ping my local server IP
How to fix this problem?
