Live-Data via Generic API don´t work

Hello all,
i create a Token for the Generic API and transfer my car data via Home Assistant to the ABRP Server. It will work if i start my travel, but after around 5 minutes i will only see old data in the right corner for the SoC and the Icon for “Connect” will change to red “not connected”.
But my instants from Home Assistant send every 10 sec all the needed data to ABRP and also the changed SoC.

The next Problem is, if it work in the 5 minutes and the go to disconnet, it will switch to the SoC at the start of the travel.
Beginning: 75%
Before the diconnect will show: 73%
After the disconnect it go to 75%

What can i do to get a working connection?
HA send the Data every 10s
This is the URL i create and use with the correct data from my car.
https://api.iternio.com/1/tlm/send?api_key=[API-Key]&token=[TOKEN]&tlm=%7B%22utc%22%3A1745267096.0%2C%22soc%22%3A%2270%22%2C%22est_battery_range%22%3A297.0%2C%22is_charging%22%3Afalse%2C%22is_dcfc%22%3Afalse%2C%22hvac_setpoint%22%3A20.0%2C%22lat%22%3A48.197433%2C%22lon%22%3A11.795012%2C%22odometer%22%3A%2215158%22%2C%22capacity%22%3A77%2C%22soe%22%3A228.69%7D

It looks like 9 min but i send every 10s the new date. And at this time the SoC has to be 73%. Like the next screenshot.

This is from Home Assistant. This are the data i send to ABRP.

I hope you can help me to get this work, that i have the correct data in the App to plan the travel correct.

Thanks for your help
