I am facing issue my target host machines probes show red , can you please tell me whats problem is,
Restart that robot as it seems to be having trouble starting.
In IM, left pane, right click / restart.
Check the controller log - controller probe/right click/ view log and look for the correct IP address being assigned and contact established line.
also can try
highlight red probes, right click, [security] - [validate]
is this question answered for you ?
