    I have the QNAP TS-410, RAID5 (4 Samsung discs 1 TB each), ±60% used.
    It has the latest firmware, it worked ok via http:// and it was visible through Finder, under external devices until I had to reformat my MacBookPro (corrupt OSX).

    I did re-install the MBPro OSX (latest Sierra) en recovered my hard-disk content from my external back-up disc (not my QNAP) with Time Machine. The MBPro works fine again.
    However, since then I don’t see my QNAP anymore, not in Finder, not through http://, and not with QFinder Pro.

    The QNAP is LAN connected, the same LAN as my MBPro.

    QNAP LED’s status are: (as indicated above)
    My Status LED flashes red-green every 0.5 seconds.
    My LAN status indicates activity as it flashes intermittently.
    USB and eSATA leds are off.
    I see 4 green lights above my discs.

    I’ve tried to reboot the QNAP through power-off, power-on, no result.
    I’ve reset my QNAP with the little button on the back, no result.
    The LED lights come back with the same status as indicated above.

    What to try/do next?
    I appreciate your advice!
    Thanks, Rens
    btw I’ve left the QNAP in this status for 5+ days, assuming rebuild of discs.
