At the initial login to my unRAID 6 I assigned an IP address ... let's call it "50." After setting up the boot, cache and a single data disk, and working with it, I began to have problems with is being inaccessible via webGUI. Looking at the Linux boot screen (on the unRAID box) I saw that it had a different IP than the one assigned; it had somehow reverted to the initial address that was dynamically assigned ... call that "117." Occasionally, I would see the 50 IP address top right on the webGUI but Fing reporting it at 117. Strangely, Fing would note that "this node has two IP addresses" ... how is that even possible? Alternately, or in addition to, stopping the array would sometimes result in the "Invalid, missing or expired registration key" notice. Rebooting usually fixed that, though as I type this I suspect the dueling IP addresses interfered with unRAID accessing the 'net and verifying license status. I finally gave up and removed the assigned IP address.
The other problem began when I added a second data disk. It cleared and was added, but the next time unRAID reported "Invalid, missing or expired registration key", it was seen as new upon rebooting. I have cleared the drive three or four times with at least two of those times successfully adding it to the array as reported by the dashboard and main screens.
Any ideas?
