When I boot up my PC in the past, CAM would boot up and log in automatically - I'd hear the fans spin up while logging in, then once logged in, they'd adjust to the settings that are saved. As far as I was aware, it would log in with Google account.

However, recently, the CAM software will boot up, spin up the fans, then say 'Couldn't authenticate the user'. But when I then manually click on the 'Google' button, it logs in fine.

Just in case it was a problem on Google's end for some reason, I tried logging in with my NZXT account. In one instance I received an error or 'Could not communicate with any node in cluster' (or something similar) then the other instance it said 'Invalid Password'. I then proceeded to change my password. Once changed, tried logging in again - same error - 'Invalid Password'.

On top of this, almost every time I do log in, I have to agree to some sort of usage policy. I've started having these issues since updating to CAM v3.7.8.

Agreed. The x52 works best once any version of CAM is uninstalled. I simply connected the fans to the mobo set to monitor CPU temp. Their speed increases properly when I use CPU-ID to bench. Those same fans (the ones that came with the x52) stay at the same speed when plugged into the x52 harness. I can only hope the pump knows when to spin faster because without CAM there's no way to control pump speed. I'd really like to connect the pump to the PUMP pinouts on the mobo. CAM is full of bugs that are never fixed. Temps and fan speeds are always wrong. CAM SOFTWARE IS INSULTING TRASH. A CLASS ACTION LAWSUIT IS IN ORDER HERE. nzxt needs to give the user a way to run its cooling systems directly off the appropriate mobo pinouts and bypass CAM and the firmware inside the pump housing. I'M ALWAYS AFRAID MY NEW 1950X SYSTEM WILL OVERHEAT. THIS IS UNACCEPTABLE. PLEASE FIX IT. In the very least, the horrid documentation doesn't even speak to whether the x52 will use safe parameters when (not if) CAM fails, which is almost all the time.

I have tried all of these troubleshooting steps multiple times.

Go into Control Panel and click on “View Devices and Printers” then remove the NZXT USB Device/690LC/Asetek Driver/Unknown USB Device and restart your PC. Then check CAM again.

Exit out of CAM, then use another mini USB cable, you can use a mini to regular external USB cable and plug it to the back of your case. (Please note if this is the issue we can provide you with a replacement cable)

Try shutting off your PC, then plug the USB cable to a different USB header on your motherboard

If you have any of the following programs installed, try disabling/uninstalling them. These can include (Precision X, Gigabyte Xtreme Gaming, RGB Fusion, Asus Aura, MSI Mystic, Afterburner, Corsair Link) They are known to sometimes cause issues with CAM.
