Anyone encountered this while charging? "Warning: Hot adapter or outlet prevents charging - Try another outlet". The mobile connector "T" flashes once every few seconds. Chargeport "T" is solid red. This is using the gen2 Mobile Connector on a NEMA 14-30. I called Tesla Vehicle support and they think it's a possible grounding issue with outlet or Mobile Connector. I've been using the outlet and Mobile connector to charge for a while with no issues but I tried scheduled charging for the first time last night and found the message this morning. The charging actually completed so wonder if it's just some software glitch with scheduled charging.
