Working with Nport 5110 device server module

Hello All,
I have the MDR 2000 series machine installed. I am getting the test results into ignition using the Nport device server module N5110. It is sending me the results while it’s testing but when its done it shows me Error message. I am confused as is that a fault of machine or is it something that device server could not read.
Please let me know if u have any thoughts.
The snapshot of error message is attached here.

Thanks in advance.
