Hi idebmatt. Did you find a solution to the issue you were having? I also installed 4.10 on my computer and I am having the same problem. Attached below is the Swarm Log. Symptoms are the same. When I click build lighting, it just freezes and I have to close the program via task manager.
Because your 8008 Port occupied，close system Pid 4 servic registry
I was having this issue and found that I was running IIS on my machine which was using port 8008. I stopped IIS and my build worked fine. This may not be the answer for all but it’s a possible answer for those of us who use IIS for other applications. The question should be is there a way to change that default port assignment? Just wondering.
This is because Swarm is recording UE4 location to a MAGIC place which is NOT “SwarmAgent.Options.xml” or “SwarmAgent.exe.config”.
It is not documented anywhere either.
Mentioning below error there’s no UE4 under D:\Build:

I had the same issue.

Find anything using 8008 or 8009 and stop running it ( for me it was a program called air server)
Problem fixed for me.
