Swarm Setup

Hello,
I have a network with a bunch of machines setup. Swarm settings are setup correctly as far as I have read on these forums.

The slave agents all show up in the coordinator, are in the correct groups, can all ping the coordinator, ping all agents, firewalls are off, but none of them pick up jobs when build is clicked. Only the local machine.

I know it’s a broad question, but what could I look into after setting everything up correctly?

Is the coordinator log I get this error:
[EndJobSpecification] Tried to begin the job on a valid remote connection, but failed.

There are no leads after this point

Any help is very appreciated
I am using UE4 4.12

You said that you deactivated the firewall but I had similar issues and had to setup rules in the firewall settings.

For the spawn coordinator allow connections port 8009 for incoming requests.
For the spawn agents allow the program “spawn agent” for incoming requests.
