So for the last couple of months, my serves has randomly become unreachable on my local network, but all my dockers still work. 

So to try and find the problem I've had syslog running the last couple of weeks to catch whats happening when it happens, and 22:25 last night (january 28) it happened again. 

Now I don't have the skills to figure out what the errors are in the syslog, so I'm hoping someone on here can help me. 
I'm able to reboot the machine by using the onboard terminal, and when I do, it always failes to find the unraid USB stick, so I have to turn off my psu, wait 5-10 sec and then turn the machine on again for it to find the USB stick. 
Is my USB stick failing? 
Its a Samsung Bar Plus 32gb flash drive, not that old, might be coming up on 2-2,5 years, cant remember exactly when i bought it. 

Diag and Syslog attached.

Flash drive is dropping offline, try a different USB port, ideally USB 2.0, if issues persist replace it.

Thanks! 
It’s already in a usb 2.0 port, it’s been in that port since I built the server so the usb drive is probably going bad, gonna order a new one.

Make sure you have a current backup of flash

For shits and giggles I changed usb port and I'm gonna see if it happens again. At least now I know what it is. 
I had it on an interal usb to "normal" usb adapter, just so it never gets unplugged by mistake, but I moved it to the back. 
Its all the same usb controller so I don't think it should make a difference, and I don't think the internal adapter just suddenly went bad, so the most likely culprit is the usb stick. 
But time will tell. 

Okay, so my USB drive just shat its fucking pants. 
Its deteriorating quckly. 

Anyone got a recommendation for a known Good usb drive???

Don't know if I just got a dud, but my it's a samsung drive thats failing.

Adding current usb drive manufacturer

I had a Samsung Fit 128gb usb drive on hand, and I didn't wanna risk getting any more data corruption bc of the usb drive disconnecting, so I plugged that in. 
Feels like its totally overkill but, if it works it works! 
The samsung fit was recommended as well.
