Bl Touch doesn't complete it's touch off.

Hi there.
I have been using the gmax xt+ for a little bit now and it just got done with a client print that was over 100 hours.
I went to do another print but the BL touch fails during it's touch offs. It would do a couple but then the pin doesn't drop on a spot.
Tried it several times, checked to make sure the pin is clear. And it is still happening.
Made a video here:

Any ideas?
