Honestly, I can't seems to find any errors in your logs.

Can you try to run only one hashboard disconnect the two hashboard and swap cables and let see if the first hashboard will hash?
Also, try to clean all terminals the cable, and the busbar it might have some corrosion/dust/rust so cleaning it might fix this issue.

Can you tell us what pool do you mine and maybe the pool where you mine is currently offline?
