Lighting build failed (Swarm)

Hi guys,
I have moved the UE4 to the new drive. During the light building, I was getting “Unable to connect to Swarm” error. It turned out, the Swarm cache was configured to the folder, which did not exist any more due to the new hard drive. I changed its configuration through the swarm interface, and now the SwarmAgent.Options.xml shows the right cache folder. However, while building light, I get different error: UE4 just instantly writes " Lighting build failed ", while the swarm log in Swarm UI looks like this:

So, as you can tell, Swarm thinks that job is done well.

Apparently, some config is still done wrong. What should I do to solve this problem?

I had the same problem - I was running the swam agent on the local machine that the editor was running on - and it would try spawn a 2nd copy of the agent when I clicked to build the lighting… you have to have NO agent running on the editor machine - it spawns it when you run the build.
