Cetera switched websites during the year. First I was using MyAccount.Iconnect2Invest.com, then Adviceworks.
I had different logins for each and the one that appears to work (to the point of it displaying, "No 1099's available..." is the one for MyAccount.Iconnect2Invest.com.
While this is the website that is being sunsetted soon, maybe this info will help you get a bit further.
Good luck,
