Rest error on 2024.5.xx

Installation
1

From version 2024.5.1 I get Rest error fetching data.

Version 2024.4.xx works correct.

I need suggestions please.

Thanks

Can you post the REST sensor and the logs showing the error?

P.S. the http://192.168.1.200/data.jsn send data correct.

The only thing that sticks out to me is the data.jsn, but aside from that, I’m not really seeing anything. Is that on the same subnet as HA? You said it sends the data correctly, but how did you test it?

Direct the url on brownser. It works perfect till version 2024.4XX. And I have another system here, where I connect it to test it and it works.

I believe something is new on version 2024.5.XX somewhere ( but I don’t know where ) and give that errors on Rest.

The data.jsn as it show on direct Url
