Did you set the logging to super verbose? This doesn’t appear to be the full log.
The Coordinator message will appear in any log whether you’re using it or not. If you’re not using coordinator (only for networked swarm agents), then there is not need to worry about that message.
You can try using the free program TCPView and see if Swarm Agent is running on the correct port. It requires port 8008/8009 to be free for use otherwise there can be some issues that will not let it build lighting.
When you open the program make sure you have swarm agent loaded, it doesn’t have to be building lighting or anything. Then under the tab for Local port click this so that it lines them up numerically. Then you can locate the process name for swarm agent. Let me know which port is being used.
