Try booting something different on proxmox like an ubuntu live desktop, just to make sure networking is working there. Seems like haos can’t talk to the Internet.

If a controller is still connected (Bluetooth?) it may be a controller order issue, you can try reordering them.

Also the alternator absolutely takes more power from the engine in proportion to how much energy it’s putting out.

Why does this only work in Hondas? What about this cares about the car?
