Problem

I am stuck in SW:TOR in the Knights of the Fallen Empire Chapter 11: Disavowed.  

I have reached the end of the area with Aric Jorgan, and have to disable three color nodes to disable the force field to proceed the quest.  However, as I reached the yellow and last node, I clicked it and went back to the gate. When I went back, the force field was still up. I tried everything: Resetting the mission and logging & coming back on to try again. This did not help.
