Why does the editor crash when building lightmass?

When I’m building lightmass I receive below error:

2973-swarm.png

I’ve attached also Swarm Agent screen.

Certifiacte check has failed…
SwarmCoordinator failed to be initialized.

Please help.

Is it the Swarm Agent that’s crashing? If yes, can you go into the Swarm settings and enable verbose logging? Perhaps that will provide some more information on what is happening.

Does it happen with any map or just a particular one?
