I set up MioNet and the WD Photos app on my iOS devices last week, and it was working very nicely.
This week, I started getting a “Device is offline. (668)” error message when trying to remotely access my media using the WD Photos app.
The only solution? Go in to the HTTP UI and reboot the device. This fix is temporary however. Try to use WD Photos again the next day and sure enough you’ll see the same Error 668.
Another observation: while WD Photos tells me the device is offline, it’s actually not, because it can be accessed from local computers through AFP or SMB in the file system. So this has more to do with MioNet/remote access features.
What’s the problem and how can it be fixed?
