Unreal Engine freezes on build lighting

When I run that with the swarm agent running, this is what I get:

TCP 127.0.0.1:49441 127.0.0.1:8008 TIME_WAIT

As for the firewall, I had already tried deleting all the rules for anything Epic Games and UE, even turning off the firewall, and that didn’t help.

Regardless, thanks for your tips, it’s always good to try new things even if in my case they won’t work, hopefully they will for somebody else.
