Thunderbolt issues on NUC11PABi5 front panel is fine, but the rear one is not woring.

[Justin666]

Hi Guys, my new NUC 11 has a wired problem with the thunderbolt port . When I use the thunderbolt port of the front panel can light up my monitor with usb-c calbe (AOC u2790pc that has a type-c port), but with no signal if use the thunderbolt port of the rear panel.  when type-c cable is connected to the display via both TBT ports , the USB hub of the moniotor can work normally. I have reset the BIOS by clearing the jumpers on the motherboard and reinstalling all the drivers like as the Graphic ，TBT ， chipest even as the monitor's , and i changed a new cable with 40gbs full speed but the problem isn't solved.

i sent the inside messege via intel support one week ago , but no any  reply. 

Any body can help me?
