4k can't connect to HD anymore

it worked for half a year and all of a sudden it doesn’t find the HDD. I checked the HDD it works normally on my Linux Mint box. Everything is there,
I’m on v1 June 2018
My log: http://paste.osmc.tv/gezininipa

At the same time I figured that SSH connection stopped working too.
I rebooted several times, unplugged USB hub and HDD already
Any ideas?

Is the disk externally powered?
Either there is a fault with the drive or it’s not getting enough power to spin up.

the HDD works perfectly fine on my PC, I can play any file.
And yes, the disk is powered externally since many months now. I never had an issue…

ah, and there’s this sound coming of the HDD, if they vero can’t find a path. I’ll check if the power supply broke.

it came back after i unplugged the HDD from the externally powered hub and the hub from the vero several times. Strange.

I’d backup your data if it is important.
