Hi,

The error message you've provided indicates a problem with the agent's ability to send heartbeats to the master. This can occur due to various reasons, such as network issues, firewall settings, or misconfigurations.

Check the master server is available and reachable, check the network/firewall settings in the system, re-check the agent config files regarding the hostnames, port numbers etc...

Regards,

Chethan YM

Sanity Check:
Since you are installing, I am under the impression that your version of CM/CDP is compatible with RHEL8. Please consider reviewing our Interactive Cloudera Support Matrix.
https://supportmatrix.cloudera.com/

Also, The highlighted ERROR snip indicates the concerned CM agent is unable to send HB to the CM Server. 

Is this happening to only one CM agent or multiple ones? Additionally, Have you checked the networking parameters of this node as mentioned in the previous update?

Let us know how it goes.
