When configuring cassandra.yaml, take note of the following:
There is a space before each IP address for parameters "listen_address" and "broadcast_rpc_address". The space is required for Cassandra to start.
When entering the parameters to configure cassandra.yaml, be sure that there is no '#' (pound sign) or 'space' before the parameter name. If there is a #, for example, #broadcast_rpc_address: 10.1.1.123, this value will become a comment. If there is a space before the parameter name, for example, <space>#broadcast_rpc_address: 10.1.1.123, you will get an error after starting Cassandra.

They mean that you have specified the IP address10 10.1.1.123 during TWCloud installationTeamwork Cloud installation, however, your hostname is resolved to loopback IP127 127.0.0.1.
You can configure how your machine resolves the hostname from the hosts file. The location of the hosts file:
On Linux:/etc/hosts
On Windows:%SystemRoot%\system32\drivers\etc\hosts
You can check what IP address is resolved from the hostname by using the following steps:
On Linux:
Execute the following command
command
Code Block
language
bash

$ resolveip -s $(hostname)
On Windows
Step 1: Find hostname of the machine.
