EB3A no bluetooth connection-bluetooth dead?

Just received my EB3A yesterday. Downloaded the app, connected it, they paired. No problem. This morning I open the app, and I keep getting 404 error, communication timed out. Tried it while on grid power, turning unit on/off, nothing. Checked my phones BT settings, it was on, but the EB3A did not show up as an available device. I tried to reinstall the unit manually, but it times out with the 404 error.
Is the bluetooth on the EB3A dead after one day?

@MaxWedge Is the problem now solved?
You need to log in to your account before connecting to the device with Bluetooth. 404 means the network is not good
