Error 400 Bad Request on any POST request

[infeeeee]

Hello

If I try to click on any togglables, I get an error 400 from HA. States are working perfectly, and I get the list of switches and sensors in preferences, so connection with HA is working, the problem is somewhere in the json data.

From the same computer I can change the switches with curl.

I tried to debug it, and found a strange thing with wireshark: if I send the POST request with the extension data it is sent as Line-based text data, while if I send it with curl, it's as a json.

Screenshots from wireshark:
