Horde Workstation Agents not helping

Development Pipeline & Plugins

We have started to test Horde Agents as Workstation on user machines.

Things are working quite well, but sometimes in the evening some agents do not seem to help at all even though the machines are not being used.

Do you have suggestions on what the problem could be or how to find the issue? The behaviour is not consistent, so it is rather strange.

Thanks,

David

The logs of building and the lease logs on the horde server may have some clues.

Hi, yes if you could send the logs and config setup that will help. Do the agents receive work during the day but the same agents not receiving work at night?

Hi David

In the screenshot given the time when no tasks are run is between 6PM-9AM could there be the possibility the user has turned off, logged out or locked their Windows computer at the end of the day and disabling the agent?

You could look at using a Dedicated mode and have the agent run as a Windows Service, this can be more reliable then Workstation mode, https://dev.epicgames.com/documentation/en\-us/unreal\-engine/horde\-agent\-deployment\-for\-unreal\-engine\#runningasaservice

When running as a service each workstation will need to have a Token value set in the Agent Settings to authenticate with Horde https://dev.epicgames.com/documentation/en\-us/unreal\-engine/horde\-agent\-deployment\-for\-unreal\-engine\#registration

Hi Matthew,

we are using Horde Server MSI Installer version 5.6.1-44447532 and the agents are downloaded from the server.

There is no particular setup, here is the Unreal Toolbox configuration:

{
  "mode": "Workstation",
  "idle": {
    "minIdleTimeSecs": 60,
    "minIdleCpuPct": 70,
    "minFreeVirtualMemMb": 256,
    "criticalProcesses": []
  },
  "cpu": {
    "cpuCount": 28,
    "cpuMultiplier": 0.5
  }
}

Screenshot from horde server shows no leases during evening/night

[Image Removed]The attached agent log from yesterday only has lines like this:

2025-10-23 22:41:04.071 +02:00 [INF] Agent capabilities queried in 6 ms

2025-10-23 22:46:04.066 +02:00 [INF] Querying agent capabilities… (may take up to 30 seconds)

Is there anything else I can look at or enable to find the issue?

Thanks,

David
