Signal loss every 3 seconds



I am having some trouble setting up the 4K.
I can see the captured video in an external software, but only for ~3 seconds, then the image is black for 3 seconds and appears again. When I open the Epiphan Configuration Tool, I can see that the signal is lost every 3 seconds and then reappears. This behaviour is continuing.
I have connected the Framegrabber to USB3.0 and the LED is blue.

I this a known issue? I there a solution to solve this problem?
