PlayBook running 2.1.0.840 getting "66048" Update server connection error

As the title states, my PlayBook running 2.1.0.840 is getting an error when I attempt to connect to the update server:

"There was an error connecting to the update server.
Please try again later (66048)"

Could this be a prelude to a general roll-out of Tablet OS 2.1?

(general internet connectivity is fine, including the Browser and App World)

EDIT: my other PlayBook running 2.0.1.668 gets "You currently have the latest software installed"... so, apologies if this is a totally false alarm.

Apologies accepted.

Failure to connect to the update server means nothing. I'm not bashing you, but I guess it is worth mentioning every now and then.

One of my PB received a 1 mb update this morning. My other PB has not received an update and I also get the error message when I check for updates. Both PB"so are on 840.
