I have the same problem with Gosund SP111 Smart Plug with the newest ESPHome 2024.7.3 Aug 24 2024, 15:16:30. On older softer it worked as intended.

I found one device esp32 s3 super mini from aliexpress that I can use api for toggling lights, but even stranger is that I can use both GET and POST to toggle lights.

web_server config from this device.

web_server:
  port: 80
  local: true
  ota: false
  include_internal: True
  version: 3
  auth: 
    username: !secret web_user
    password: !secret web_password

Also the device that works uses the same user and password that devices that don't work.
