I installed Wednesday’s update and that’s when I first encountered this problem. I have it on a 10.0.0.x network. After the update on Wednesday I was able to access the web dashboard and then, while trying to do a backup, it locked up on me. I got out and then have not been able to get back in since. For a while I lost all access to the device. After powering off and back on, I am able to access the data but I still can’t access the dashboard. I have cleared the cache, I have used multiple browsers and even tried different operating systems (I usually use a Mac - I tried on both Windows 7 and Windows 10 as well). Any advice would be helpful.
