Swarm failed to kick off

Hi,

since i’m running 4.11 from source i receive this message when i build the lightning: swarm failed to kick off
with 4.11 from the launcher i not having this problem.

i have installed the latest drivers, and my firewall is not blocking the swarm.

Thanks in advance,

problem is solved by rebuilding the unrealLightmass

Having the same issue, can you explain this more thoroughly?

the only thing i did was in the ue4.sln clicking on the rebuild from the unrealLightmass

Confirmed Rebuilding unrealLightmass resolves this issue. Sincere Thanks.

Is this something you have to do with the engine source code? I’m getting this error and I don’t currently have engine source code. Would this still fix it?

i think this solution will only work for the ue4 source code build
