My CTA 1 has power but stopped hashing. Any idea where to start TS this?

Help! =)

I have 5 Cointerra Terraminer IV's and a few are all doing the same thing. Hashing at 1/2 of what they are supposed to. some CTA 0 and CTA 1 nre between 300 - 400  GH/s. 2 are hashing at full capacity on CTA 0 but CTA 1 just sits there. I am at a loss on what to do.

CTA1 Metrics   High   Low   Avg
Core Temp 1 (°C)   33.91   30.3   31.75
Core Temp 2 (°C)   36.88   30.79   33.50
Ambient Temp (°C)   37.5   36.75   37.12
Fan Speed (RPM)   1,728   1,671   1,700
Pump Speed (RPM)   0   0   0


in the logs I see it restart but never take any shares:

Any ideas? If I was hacked the temps would be high and it would be running. but the temps are low telling me that the issue is not that it is hacked rather CTA 1 just is not working, but why?


Thank you for any help,
