Error -1074360293 occurred at IMAQdx Get Image.vi

Hello,

I have question on Vision Acquisition system;  the VI is able to "run" with serval minutes, and  there is an error that appears:

"Error -1074360293 occurred at IMAQdx Get Image.vi

NI-IMAQdx: (Hex 0xBFF6901B) Timeout"

I able to view the ip camera and acquire from it within MAX. Also, able to test on Vision Acquisition. please look at below picture. But no any image show on vi during vi run.

Any helps are much appreciated. Thanks a lot.
