I feel the same way, I've reflashed, made sure the SSD is seated well, used a USB cable to see if the hashboard was bad absolutely nothing wrong with it, temps are in a great range - I even went as far as putting it in ECO mode... after about an hour I get the notification that my miner was disconnected, log back into the dashboard to see the pool settings are once again changed..

What's odd, is it's completely random times when this happens, the first 7 days were flawless mining and then randomly on the 8th day it started changing the pool settings - again sometimes it'll be hours, then sometimes I have to sit there and change the pool settings 5 times within an hour - reboot - let the node start - start miner (sometimes have to click start 5-10 times before it'll become active to where the dashboard pops up) start hashing and then be fine and connected to my pool for 10+ hours..

Makes absolutely no sense other than a back door or something.
