Hi guys, i have been trying to build the lights in my project, but swarm agent failed everytime. I tried all the solutions that i found in this answerhub. The log error in Swarm Agent is:

Follow along in that part of the Wiki I made to resolve your issue. Ultimately, once you know what process is being used that prevents Swarm from using the correct port you’ll need to solve that locally on your machine. This isn’t something that I’ll be able to really walk you through, so you’ll need to use Google and a little bit of digging. Hopefully that helps you figure out what’s going on.
Hi everyone, I also have a problem with the swarm agent. I can not make it work on the net with my second pc, on the first machine, the one where I installed unreal4, in the SwarmStatus tells me Waiting for remote access to become available, but do not leave. On the second pc in the log i by the following errors:
[StartJobExecution] Exception was: System.UnauthorizedAccessException: Access to the path ‘C:\Program Files\Epic Games\UE_4.15\Engine\Binaries\DotNET/SwarmCache\Jobs\Job-F0357984-4E93988B-4A72B680-490D7F86\UnrealLightmass.exe’ is denied.

To set the swarm I followed this video

it’s because of materials with duplicate names. Try searching for them in your content browser and renaming the dupes
