Yes. I uninstalled the software and then re-installed it and I am no longer getting the error message.
But, there seems to be an issue with the interface between the hardware (MyCloud EX2) and the software.
I installed my system a couple days ago and initially did a backup that was around 200 GB. My hardware said I had 2.9 TB of storage available when I first started. I did my backup to a Share named “Smartware”. But yesterday I decided to delete that Share with the understanding that it would delete my data also.
I thought if I uninstalled the Smartware software it would recognize the available space I should have on my hardware but for some reason it thinks I only have 2.7 TB of space available.
I am not sure why it thinks that a drive that should contain no data still has about 0.2 TB of data on it.
I setup a backup to a share then decided to renam the share and reset the backup. The software thinks I still have the old name and gives me the cannot authenticate message to the old name. The new name and backup is working fine. How can I get rid of this message?
