Always get the error 408 (vehicle is offline) when send to DOMAIN_INFOTAINMENT by `signed_command` API

[Whirlwind]

I send the session_info_request cmd to the DOMAIN_INFOTAINMENT and DOMAIN_VEHICLE_SECURITY by the BLE, everything works.

But I send them by the Fleet API, the DOMAIN_VEHICLE_SECURITY works but the DOMAIN_INFOTAINMENT always failed:

API GET: /api/1/vehicles/xxxxx
{
    response =     {
        "access_type" = OWNER;
        state = online;
        vin = xxxx;
        .....
    };
}

I am sure the vehicle is online, I am in the car...

If you're able to reproduce, could you try (1) running tesla-control with -debug and (2) checking to see if the mobile app works over the Internet?

[Whirlwind]

I will try it. But the command send to vcsec works by signed_command, I can unlock and open the door.

The commands to Infotainment domain failed.

By the way, my region is China, and the tesla host is https://fleet-api.prd.cn.vn.cloud.tesla.cn. I am not sure it is a bug for the china region.
