What version of the CMC are you trying to log in with?  If you're on 12.6 or 12.7,  it can only manage 11.5 or higher nodes IIRC.  If you've done the software downloads religiously, you likely have an older CMC in your downloads and updates folder, see if you can install the 11.5 CMC and then upgrade the nodes to 11.5.  Then I believe you should be able to manage then in any of the 12.x versions (and upgrade the units further).
