I used to be able to hit the webserver on the powerwalls on my wired Ethernet. Starting a day or two ago I stopped being able to do so (on either http or https). The device responds to ping (ICMP echo)

Telsa confirmed on a support call that they remotely disabled the web server.
Firmware 1.20.0
I can't find anywhere where Telsla say, or even imply, that they are permitted to control your system remotely. The terms of the warranty allow them to upgrade you system, but issuing a command that disables the web server is not upgrading.
I don't know about US law, but Australian law contains a provision relating to unauthorised modification of data or imparment of communication to or from a computer. What Tesla are doing seems to be skirting dangerously close to being an actual criminal offence in Australia.
Tesla Australia have restored my access to the webserver by rebooting the gateway remotely. I confirmed with the tech guy that the gateway can also be rebooted by pressing the reset button, visible through the hole marked Reset on front panel, though it seems that not all gateways have that feature.
I had previously attempted to restart it by powering it down and up again, but I note that there are some LEDs visible through that hole, and they didn't go out. I may not have succeeded in powering it down. One may have to be sure to isolate not just the powerwall but also the solar panels, as well as turning the main power off, and then being patient.
Some logs have been retrieved from my system, so that Tesla can try to understand why the server access failed.
All indications remain that this is some kind of bug/fault, and not the result of a deliberate act by Tesla.

I performed a Gateway reset this morning. I have the same issue - no access to the web server or API.
Perhaps you were able to get Tesla Australia to do the right thing. I'd like to know if others in the US are able to get access through a Gateway reboot or not.
Thanks for the update. I did a gateway reboot this evening, and got web and API access back as well. My gateway doesn't have the reset button, so completely powering it down was an interesting exercise.
My notebook and monitoring PC can now both connect, and I have data flowing back into my Home Assistant and emoncms servers. However, nothing else on my network can get web access nor ping the gateway, including access through the gateway AP, so it's still not fully working. This is similar to how it started to degrade soon after the 1.20 update, so we'll see how long it lasts this time. At least I know how to get it going again.
