Have been charging my new X/LR at home in Vt, on my 48AMP CCS charger (using J1772 adapter) since getting delivery 12/27. Today, at zero Fahrenheit, I got home, inserted the charge cable, and - nothing. The pale blue ring light went out, then no lights at all; phone app showed not connected. Tried several more times and eventually got a dark blue ring light. But phone app still shows not connected. Checked obvious things like snow in the plug, etc. Seems clean. What to do next? I have 60% charge so not desperate at the moment. But it is -20 now and so we'll use a bunch of power tomorrow if we have to warm up the car on the battery. Anybody else have this recently? (I know there were a bunch of charge cable issues a year ago, that seemed to have been software related, and resolved.) Thanks for your help!
