Error 0xBFFF0011 Occurs during LAN communication

I program with LABVIEW2017,VISA2017.

In MAX, an oscilloscope was added to communicate with the LAN, and the communication was normal at the beginning. After a period of time, the device could not be opened, and error 0Xbfff0011 was reported. Only after the device was added again in MAX or the computer was restarted, the communication could still occur.

Now I'm only going to turn this on once in the entire program,. But I've tried to write a program that keeps turning it on and off, and it doesn't go wrong, so what's the problem.
