Hello Eric

If the message is seen in the Control Room when the status of a Runtime Resource is being queried then it may indicate that the connection between the two machines is blocked. Typically, firewall rules may be blocking the Runtime Resource's configured port. Try connecting the listening port on the Runtime Resource from the App Server and see if you can reach it. 

The Runtime Resource firewall will need to allow Outbound connections on the configured startup port, and on the Callback Port, and the machine which is querying the status (via Control Room) will need to accept Inbound connections on the same port numbers.

For more information, you can refer the Knowledge Base as linked below:

Thanks Karan

We have tried to open all ports (inbound and outbound, TCP and UDP) on runtime resource, but the issue keep existing. It is quite strange that other machines install OS by using the same ghost file, but they are work well without any firewall configuration.
