Ubuntu One won't sync; cannot see account info

[seattle vic]

Binary package hint: ubuntuone-control-panel

Running 11.04, 1.6.2-0ubuntu1. U1 is constantly trying to sync and upload files but never finishes. The dialog box saying that it is uploading flashes every couple minutes. In the control panel, there is no account information shown, with the message, "The information could not be retrieved. Maybe your internet connection is down?"

Output of u1sdtool -s:

State: WAITING
    connection: With User With Network
    description: waiting before try connecting again
    is_connected: False
    is_error: False
    is_online: False
    queues: WORKING

I will add that U1 seemed to be working well when I upgraded to 11.04 a month ago, but for the last 2 weeks it's rarely sync'd at all.

Status changed to 'Confirmed' because the bug affects multiple users.
