N260 problem even though power connector installed

[rcspencer1]

I have an older heat only gas/hot air system, and the thermostat wire only has white and red.  So I installed the Nest and was directed to install the power connector, which I did.  It worked fine for about a week and then started giving me the N260 error.  I checked all the wires and everything is correct (I mean it's only a few wires), but can't get the problem resolved.  Any help you can provide would be greatly appreciated.

Could you please give us a photo of the wiring of your Nest Thermostat  and on how the Nest Power Connector installed? Then, please check the power read out and the wiring diagram of your thermostat and share it with us.
