Hello,  To enable Cloudera Server High Availability, I configured a HaProxy.  - Port 7183 is used for CM UI - Port 7182 is used for cloudera agents While CM UI is working, there is no heartbeat from CM hosts. I got the following error from /log/cloudera-scm-agent.log   [26/Nov/2025 11:51:34 +0100] 62213 MainThread agent        WARNING  Port is being used by CM Agent: 7182 [26/Nov/2025 11:51:34 +0100] 62213 MainThread agent        ERROR    Heartbeating to my_load_balancer:7182 failed.
