Eclipse Hono - ConnectTimeoutException when starting the Command Line Client in the terminal for sending commands - eclipse-hono

Question

I am following the Eclipse Hono getting started guide and using the sandbox environment.
I opened git bash terminal and used this command for starting the device to receive commands:
mosquitto_sub -v -h $MQTT_ADAPTER_IP -u $MY_DEVICE#$MY_TENANT -P $MY_PWD -t command/+/+/req/#
I opened another git bash terminal and used this command for the application client to send commands to the device:
java -jar hono-cli-*-exec.jar --hono.client.host=$AMQP_NETWORK_IP --hono.client.port=15672 --hono.client.username=consumer#HONO --hono.client.password=verysecret --tenant.id=$MY_TENANT --device.id=$MY_DEVICE --spring.profiles.active=command
But I get this exception when I use the above command:
21:41:45.504 [main] INFO org.eclipse.hono.cli.Application - Starting Application v1.3.0 on DESKTOP-4SV0QNN with PID 9768 (C:\Users\HP\hono-cli-1.3.0-exec.jar started by HP in C:\Users\HP)

I have set the environment variables MQTT_ADAPTER_IP, MY_TENANT, MY_DEVICE in the application client terminal and MY_TENANT, MY_DEVICE, MY_PWD, MQTT_ADAPTER_IP in the device terminal.
This is the jdk version in my system:
C:\Users\HP>java -version
java version "11.0.7" 2020-04-14 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.7+8-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.7+8-LTS, mixed mode)
Please let know how can I fix this.
