Cannot connect to remote kafka broker even after configuring advertised listeners

I have a vm created in GCP and I setup kafka in it. I had changed the advertised listeners to the external public ip of the vm.

enter image description here

But when ever I try to connect from the local laptop I keep getting this error.

enter image description here

I checked the connectivity to machine from ping and I am getting response

If your client (Kafka Producer) it is outside of the VM, you need to expose the following: 

listeners=INTERNAL://0.0.0.0:19092,EXTERNAL://0.0.0.0:9092
listener.security.protocol.map=INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT
advertised.listeners=INTERNAL://vm-address:19092,EXTERNAL://host-address:9092
inter.broker.listener.name=INTERNAL

Now your producer should use 19092
