Swarm Setup agent not able to connect to coordinator

I’m trying to use the swarm coordinator with my other home PCs to help speed up the build process. I got my local machine (running coordinator and agent) to connect to itself, but the swarm agent on the other pc does not connect. This is the log.

8:00:21 PM: Starting up SwarmAgent ...
8:00:21 PM:  ... registering SwarmAgent with remoting service

8:00:27 PM:  ......... SwarmCoordinator failed to be initialized

8:00:28 PM:  ... initialization successful, SwarmAgent now running
8:01:05 PM: [Network] Pinging Coordinator...
8:01:05 PM: [Network]     Coordinator has failed to respond
8:01:05 PM: [Network] Coordinator ping complete

I’m not sure what I’m doing wrong. My settings for the PC are:

AllowedRemoteAgentNames = *
CoordinatorRemotingHost = 192.16

Everything else is default.
