E-Stop hardware failure?

[TK_Fire]

Looked on the forum I think the e-stop button is broken, it is triggering stops when not pressed (yes I checked buttons, reset machine, rechecked buttons).
the machine is a Optiv 443 dual Z, there are 2 stops on the machine and one on the jogbox.
my hunch is the estop on the jogbox is the one causing issues, is there a way to verify?
Can't start the machine due to the estop triggering.

error that pops up:
0x1400005f e stop button pressed (auxiliary)

This could also be a faulty jogbox, jogbox cable.

I would try opening the jogbox, and check the wiring.
On an old JB, I saw once the wire unplugged...
