When triggering a build from Visual Studios (2022), UBA starts up and its clear the build is distributed.
When triggering a build from Jenkins - the build is _not_ distributed even thought he agents are registered to the server and are using the same Build..xml.
Horde is at least partly set up correctly…but something is clearly not right since it should distribute builds from any build agent, no?
When you say “triggering a build from Visual Studio”, you are executing from a developer workstation and UBA works as intended?
What authentication are you using with Horde? Built-in accounts, or OpenID Connect?
To properly see what’s going on, try inspecting the Unreal Build Tool logs as they it’s executed by Jenkins. For example, there might be issues with authentication. If possible, post them here.
