I am on 7.1.4 and have kept getting this issue, This narrowed it down to a app last time or so I thought, removed it, and the issue stopped. So left it as that....... decided to install another app. FileFlows-Node. Within mins, cant access dashboard, now I am starting to wonder something, as the one before it, accessed /mnt, Fileflows-node access /mnt/cache by default So I am wondering if thats causes an internal crash with the GUI itself. I am going to reboot, and then move the temp folder it wants to use, to something thats more on the array or a actual proper location within /mnt/user. I am just throwing thoughts at this point. As nothing else has changed on my server but this container, and before that it was another, which the issue went away after removing.
