REST sensor to Teltonika RUTX11 API

So I have HA Container running in docker and am trying to setup a simple REST API POST to my router to get a token value. The REST API works find from testing in postman on my laptop on the same network, But in HA it is timing out connecting. Log shows

2025-06-22 02:07:07.413 WARNING (MainThread) [homeassistant.components.sensor] Setup of sensor platform rest is taking over 10 seconds.
2025-06-22 02:07:42.420 WARNING (MainThread) [homeassistant.components.sensor] Platform rest not ready yet; Retrying in background in 30 seconds

This is the code for the REST sensor:

sensor:

  • platform: rest
    name: “RUTX11 Token”
    unique_id: “c137268b-e19f-4cb9-ba69-6671d7fca8ba”
    icon: “mdi:router-wireless”
    resource: https://192.168.1.1/api/login
    verify_ssl: false
    method: POST
    scan_interval: 240
    payload: ‘{ “username”: “myuser”, “password”: “mypass” }’
    headers:
    User-Agent: Home Assistant REST sensor
    Content-Type: application/json
    value_template: “{{ value_json[‘data’][‘token’] }}”

Weird thing is, it use to work, but stopped working and cant figure out for the life of me what has changed.
