Since v4.0 I noticed that my device gets into a funny state where it askes me to log in (the web UI) so I enter username/pass. I see the dashbroad extremely briefly and then I get kicked back to the username/login screen over and over again.
It doesn’t correct itself until I reboot the device. I haven’t looked into the logs, but when it does it again, I’ll post them here. Unless someone else has seen this behavour and knows what the cause of it might be.
