Hello Tesla Fam, 2020 M3P not charging with Gen2 MC with 14-50 adapter, Charge Current is 5A Max. App reads 0mi/hr +0mi 0/0A 240V. Gen 2 MC is streaming green light and charge port on M3P is flashing green. Two 50A breakers in my panel routed to outdoor outlet. Using 10ft extension cord to help reach my car. Any suggestions on why I’m not able to charge at 32A at my house?

Lately there seems to be a rash of problems with mobile connectors using the Tesla 14-50 NEMA adapter. My suggestion would be to see if you can plug your setup (minus extension cord) into somebody else's known working 14-50 outlet and see what happens. Alternatively, you can try going to your local Tesla Service Center and see if they have a 14-50R and test your equipment. If it also does the same, swap out the NEMA 14-50 adapter with one that is known to be good and try again.
You can try disconnecting the NEMA 14-50 adapter and re-insert it (hard) into the mobile connector and then try charging. It might just be a bad connection with the adapter.
Another possible troubleshooting item, but it would cost some money, would be to get your hands on a 14-50P to 14-30R adapter cord and use a 14-30 NEMA adapter with your mobile connector. What I'm suggesting is to not use your existing 14-50 NEMA adapter with your mobile connector and see if the problem goes away, If it does, then your 14-50 adapter is the problem. If it turns out you still can't charge, then it could be your mobile connector.

Given the rash of reports lately, it's almost certainly a bad 14-50 adapter on the Tesla UMC. There's a bad batch of adapters out there.
Get a new adapter. I’ve read about 5 different cases of this and experienced it myself, with three bad adapters in a row. Check out This thread.
