According to your logs the control board seems can't detect all hashboards properly.
Have you ever tried to change the pool instead of using miningrigrentals?
You can try
https://solo.ckpool.org/ or ViaBTC pool just to test and maybe the issue is due to the pool you are using.
So i remove connectors on one dashboard and took 2 hours on re fitting and removing all the flux.
Heres the new log codes!
