I had this same problem on one of my pod, i left it alone and after an hour or so it fixed itself.
Weird but I have them all working now.
Huh, I have one that runs great at 200 and another that went down to 6 chips, was repaired by sidehack and worked great for a few weeks but now shows zero.
I tried powering off for 9 hours and still had zero.
Did you do anything else after the "rest" that I can try?
Edited for clarity
