Power LED is blinking R7800

[gattag]

I cannot start to use my ReadyNAS 212 while after the initial setup (Power cable, LAN cable) I cannot discover product via ReadyCLOUD. The power button LED is still blinking after a whole day. Tried to push backup button, did a reset button with no luck
Tried with or without disk. Seams no difference
RAIDar for Mac can see the NAS but that's all.

Please advice me how can I make this product working

 Thanks

After OS reinstall I tried a reset again and this helped

You might want to check disk health by downloading the log zip file from the web ui.  Look in disk_info.log for the SMART stats.

Thanks!
Not sure what it was but after an OS reinstall and after that a factory reset made it working. Updated the firmware and everything seems fine

The disk was healthy. I can use it now without any problem
