The day after a major thunderstorm, I went to drive my Tesla 3 2021. It is powered in my garage with a mobile connector and an NEMI 14-50 power source. There was some hesitation in removing the adapter, but it did come out and the port closed. I got into the car and saw "charging equipment not recognized" (see attached), "unable to drive", active alerts: CP a004. It also said the port was still open and I had to click to say it was closed. My car did charge and I was able to drive though the warning stayed. When I got home, I tried a soft reset twice with no change. The mobile connector was "all green" but it would not open the port. When I plugged it in, it did charge the car and the screen showed it charging. I had a spare mobile connector never used and switched to it. It was recognized and charged the car but this AM the same thing happened and when I got in the car a new warning on "charging equipment not recognized". I put in a service appointment, but it will be a couple of weeks. Any suggestions? Is it the mobile connector or a car issue. Anything I can try? Thanks.
