Error when running cassandra on Google Cloud on external ip - Failed to bind port 9042 on 34.89.109.98

问题

I am trying to make Cassandra run on Google Cloud using external ip of the VM. But I am getting error Failed to bind port 9042 on 34.89.109.98. As far as I can see, I have followed the rules of setting firewall rules but I am still not able to resolve the issue. I have attached the pics of my configuration for your reference.

1) The firewall rule is

2) The list of all the rules is

3) The VM is

More Information I followed the steps in https://linuxize.com/post/how-to-install-apache-cassandra-on-debian-9/ to install Cassandra. This automatically started cassandra. Then I killed cassandra, changed the ip address to external IP in cassandra.yaml file and started it again. It didn't work. Then I started working around with VPN settings.

Part of the message dump after I issue the command to start cassandra /usr/sbin/cassandra -f

Within the Cassandra cassandra.yaml file you can bind your Cassandra server to an IP address on which it is listening. The default is 127.0.0.1 (localhost) and is not suitable for external connections.

The address values you can use are the addresses that the Compute Engine has associated with it. These can be discovered using:

ip addr

It is important to realize that a Compute Engine may appear to have a public IP address when shown in the GCP Console, but that is not a network interface on the Compute Engine. In the example in your original question, the Compute Engine IP address would be 10.154.0.4. This is the address you want to set in your configuration file.
