2024.5.3 Rest Error fetching data

Hi everybody. I installed the 2024.5.3 and now I get Rest error fetching data.

When I add the url on the browser the source is working correct. Somehow something is wrong.

Anybody have this issue?

Here are the sensors I get the error.
rest:

  • resource: “http://192.168.1.200/data.jsn
    scan_interval: 10
    sensor:
    • name: “ELWAXX_Power”
      unique_id: “elwaxx_power”
      value_template: “{{ value_json.power }}”
      unit_of_measurement: “W”
      device_class: power
      state_class: measurement

    • name: “ELWAXX_TEMP”
      unique_id: “elwaxx_temp”
      value_template: “{{ value_json.temp1 / 10 }}”
      unit_of_measurement: “°C”
      device_class: temperature
      state_class: measurement

    • name: “ELWAXX_Target”
      unique_id: “elwaxx_target”
      value_template: “{{ value_json.ww1target / 10 }}”
      unit_of_measurement: “°C”
      device_class: temperature
      state_class: measurement

When I use the 2024.4.3 everything is working correct.
The issue start after the 2024.5.1

Any suggestion or help? Thanks in advance.

P.S. the http://192.168.1.200/data.jsn is working/provide data correct

Is that resource really correct? Typically those should end with .json but in your case it’s .jsn.
Does it work from your browser to get the file?
