Swarm Coordinator is not coordinating

Yes, ping to machine name works. It resolves IPv6 address.

We had Windows Firewall only, with SwarmAgent allowed. We tried disabling Win Firewall though, same issues.

We can also access each other’s shared folders normally.

Finally, we tried entering our IPv4 addresses instead of machine names. Still nothing.

But then… I see this on my brother’s log:

 ...... initializing connection to SwarmCoordinator
 ......... using SwarmCoordinator on GOG
[PingRemoteHost] Successfully pinged GOG with GOG
[Ping] Communication with the coordinator failed, job distribution will be disabled until the connection is established
Exception details: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 192.168.0.110:8009

I go on my router’s config and add a port forward on port 8009 to my computer (192.168.0.110). My brother’s log now reads:

 ...... initializing connection to SwarmCoordinator
 ......... using SwarmCoordinator on 192.168.0.110
[PingRemoteHost] Successfully pinged 192.168.0.110 with 192.168.0.110
 ......... SwarmCoordinator successfully initialized

But it still won’t distribute! My brother’s machine is still “Available, unassigned”.
