Powerwall has seemingly randomly changed its password

Last night my Powerwall 2+ performed a firmware update and now it seems to refuse the password that is printed on the label, even when it was working fine before. Has anyone else experienced this?

Heres the error in the docker container:

I also can't connect to it using the Tesla One app, even when scanning the QR code. It just says the WiFi network password is incorrect.

Additionally, the firmware version it is now on is 24.12.3

Figured it out, the firmware update changed it so that it only uses the last 5 characters of the password for the non-tedapi creds, instead of allowing the full password.

Interesting! Thanks for the note on that @Meowcat285 ! How did you discover that?

I decided to simply try the last 5 characters because thats what you had to do to log into the web ui as a customer.

I'll add that as a note to the README troubleshooting.
