Render host is not responding

[ha_nhi]

Hello guys, I have this error when I just livelink from 3dsmax to vantage, my vantage will disappear after 30 seconds or more. I don't know how to fix it. If anyone has experienced it, please tell me how to fix it. I really appreciate that
This is my rig:

Could you give more details? Does the link work initially (you said it drops after 30 seconds)? What is the state of Vantage when this happens - is it rendering, does it load the scene, does it hang, etc? Is Vantage listening for connections - check the Live Link menu in Vantage - it should say "listening on port 20701"?
