Swarm Agent not connecting

Hi, I wanted to connect two computers with swarm agent, but they won’t connect. They both share the same network. When I set all the settings in the SwarmAgent.exe and open the coordinator in the main computer (XAVIALIENWARE17) it does appear in the list. But when I set the settings in the SwarmAgent.exe in my other computer (X51XAVI) it doesn’t appear in the list.
Please help! Thanks!
