Agent websocket topic not found error when registering additional components

Question

I am trying out the new ArcGIS Monitor.  I was able to get it installed, connected to a Postgres DB, and added a server component.  However, I am having issues adding additional components.  I get an "Communication timeout between Agent and Server" error, followed by "Agent websocket topic not found.  Check agent connection properties".  If I go to the Agent tab, my agent says that its disconnected.  Restarting the Windows service gets the agent to connect again, but the same issue happens next time I go to add a component.

Also, the component I did register successfully doesn't show any metrics.

This is an error that I found in the logs:

Websocket closed; reason: {"channel":{"name":"agentsync:*","_onConnect":"AgentSyncController","_channelControllerListeners":[{"eventName":"close","method":"onClose"},{"eventName":"error","method":"onError"},{"eventName":"ping","method":"onPing"},{"eventName":"message","method":"onMessage"}],"subscriptions":{},"_middleware":["auth:agent"]},"emitter":{}}

Hello, was there any fix for this issue? I am experiencing a nearly identical issue when registering Linux hosts. Thanks!

Hi @Justin_Greco,

To confirm, you've installed ArcGIS Monitor 2023 on a Windows OS machine. As far as you know, it is working properly, can you please confirm? Perhaps try registering another component?

Then, you attempt to register a Linux host machine with Monitor,

Please check that you've met all the requirements here, Register Linux hosts

Hope this helps,

Correction, I only installed AM Server and AM Database on the machine.  I did see where it said to install only AM Server or AM Agent.  I believe I have this all set up correctly, not sure if there is something I am missing permissions wise on the RHEL 8 server.  I also just had a fresh Windows 2019 server provisioned for the new version.  I am seeing the same issue here as well.

When I add register the Linux server, the Status is Unknown and says Alerting is disabled.  Then when I go to the Metrics tab, there are no metrics listed.  Then when I go to the Monitoring>Agents tab, it shows the agent for the server where AM Server is installed is disconnected.
