Most likely its that your mid server requests are being blocked or that it doesn't have a route to the IP ranges you defined.  Some handy troubleshooting tips can be found here

Whats the resolution for this error?

[sukran]

Two possible may impact discovery

1 device isn't alive 

2 IP address blocked by firewall

Hello Sukran,

This is because the device is not active while discovery is trying to discover. You should try pinging the device through any of the mid server .(ping 10.*****). If the device is active check for the port to be open.....

Thanks
