Scanning network folder terminates connection to Pi

Hey guys,
I have just set up my RPi 3 with a WINGONEER PIFI Digi DAC+ HIFI DAC PCM5122 and mounted an audio folder on my network share (> 300 GB). Once volumio starts to scan the files, I lose connection (both from my laptop via gigabit ethernet and my phone via wifi). My Pi is connected via Wifi and Ethernet, if that is an important information.

An idea anyone?

Thanks in advance.


Can you access the UI at a later time, & does the scan complete?

No, I can’t. At least I have tried to access volumio several hours later at it wasn’t possible :-/
