Hi Difegi -

Take a look at the Swarm Agent Troubleshooting Guide, A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

After trying the steps there and you are stilling having issues, please report back here with your results.

Thank You

Eric Ketchum

this solution not helped get rid of the problem! =(

Can you provide more context to your project?

  • Is this just a scene you’re building lighting for?
  • Are you attempting to use Swarm Coordinator for use with multiple computers to build lighting or a build farm?
  • Can you build lighting in a new blank project with the default map?

Thank you!

Tim

Hello!
To build lighting in a new empty project, you can’t, you receive the error Failed to connect to Swarm!
Swarm Coordinator use only on one computer!
Create a new project and click open level and new level, then create a simple landscape and building a house from the brush, that would just check the build! he runs immediately writes 100% and after you get the error!

here is the log Swarm Agent

If you’re only using your computer, then swarm coordinator is not a worry in this sense.

Couple of things:
