rosi-shapeblue opened a new issue, #11620:
URL: https://github.com/apache/cloudstack/issues/11620
### problem
When deploying new Console Proxy VMs (CPVMs), the CloudStack UI occasionally
displays Agent State = Disconnected (grey dot) even though the management
server, API, and database confirm the agent is connected and in Up state.
The discrepancy is resolved after stop/start of the CPVM, suggesting a UI
polling or state refresh issue rather than an agent connectivity failure.
### versions
ACS 4.21, KVM
### The steps to reproduce the bug
1. Configure console proxy limits to force new CPVMs (from Global settings):
`consoleproxy.launch.max: 3`
`onsoleproxy.session.max: 10`
`consoleproxy.capacity.standby:25`
2. Restart management server to promote the changes to the config
3. Observe the System VMs list in the UI after the new CPVMs come up.
### Evidence / Actual Result:
UI shows v-9-VM with Agent State = Disconnected (grey dot).
API/DB show the CPVM host is Up:
SELECT id,name,status,mgmt_server_id,last_ping FROM host WHERE id=8;
+----+--------------------+--------+----------------+
| id | name | status | last_ping |
+----+--------------------+--------+----------------+
| 8 | v-9-VM/10.0.59.204 | Up | advancing |
+----+--------------------+--------+----------------+
Management server logs show continuous pings and load reports:
```
Ping from AgentAttache {"_id":8,"_name":"v-9-VM/10.0.59.204", ...}
ConsoleProxyLoadReportCommand {"_proxyVmId":"8", ...}
```
After stop/start of the CPVM, the UI correctly updates to Agent State = Up.
### What to do about it?
Once the CPVM connects and reports to the management server, the UI should
update Agent State = Up in sync with the backend, without requiring manual
restart or page refresh.
