ue4 net rendering - swarm "failed to ping"

Hi all,
I’ve been having a problem with the network rendering in ue4. The swarm coordinator sees the computer in the network, but when i try to build the light the swarm agent in the network computer shows an error: “failed to ping (name of the computer with the swarm coordinator)”
I’ve been trying to find some clues in other places but without any result.

I’ll be really grateful if anyone could help me.

Cheers!

Try to setup your firewall.

For the pc with the connector you have to allow incoming requests on port 8009.
For the pcs with the swarm agent you have to allow incoming requests for the “swarm agent” executable.
