Wall Connector suddenly limited to 44A

[dansev]

I have had my Gen3 Wall Connector charging at 48A since it was installed. It's on a 60A circuit. Here's the info from the app (with the SN blocked out). It clearly shows it can output 48A:

But today I noticed the app shows the current limited to 44A with no way to go up to 48A:

The only thing I can think of is that the setup changed within the web interface. So I tried to connect to that. First I just went to the IP where I got this screen/error that I had never seen before:

Next I pressed the button on the cable enabling the built-in wifi and connected to that SSID. Then I went to the documented, built in management IP. Same screen as above. So I downloaded the Tesla One app. The only logical option on that app (after signing in as a non-tesla employee) was to"begin install" of a wall connector. It asked for the wifi info from the box, which I entered. It could not connect.

So for now, I'm stuck at 44A. Only other thing I'll add is that my electrician was here a couple weeks ago converting a 20A/120V circuit into a 20A/240v for a new single-head mini-split for my living room. He should not have in any way touched the Wall Connector circuit, but this is the only thing that has happened electrically-speaking since I noticed this 44A limitation. All that said, something tells me if I can get into the Wall Connector setup I'll find that it has been reduced to 44A and I can jack it back up to 48A. But I can't get in there anymore!

Any help would be much appreciated!

Perhaps this is a silly question, but...how long did you let it sit there charging at 44amps? My car will regularly show 44 or 46 amps when it first starts charging, and after a short period of time, ramp up to 48 amps.

Along the same token if something is overheating it might de-rate the amperage. Is it 44 amps constant throughout the charge session or does it go down from 48 to 44 at some point?

So I just upped the charge limit and restarted charging, and it is indeed at 48A again. But....why? What happened before? I am a little obsessive about checking this stuff and never remember seeing anything less than 48A in the large center block/selector where you can reduce (or increase if it is already reduced) the charging amperage. It shouldn't be over heating. Maybe the handle just wasn't perfectly seated in the port?
