2024.5.3 Rest Error fetching data

[showup]

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

How to format your code in forum posts

Spaces at the beginning of the line are critical in yaml, and people trying to help you may want to copy your code so that they can try it out themselves, so please format it correctly when you are posting. Use the preformatted text tool (</> in the edit post toolbar). If it is not immediately visible, it will be in the cogwheel menu. [Code_format] Alternatively you can use three backticks (the key is on the far left, 2nd row on en keyboards) on their own line above and below the code. That i…

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?
