Error connecting to spectrum server: dial tcp 127.0.0.1:1234:

I run this command to find my meter ~ docker run --rm -ti -e LISTEN_ONLY=yes -e RTL_MSGTYPE="all" -e RTL_TCP_ARGS="-d 777" --device=/dev/bus/usb:/dev/bus/usb allangood/rtlamr2mqtt
but get an error code of:

Got it to show once before in testing but now it just keeps giving me this error. Am I doing something wrong or is this just not working?
Btw, yes its connected to a powered hub.

I just had the same issue, turned out I was already using the device from another container (rtl_433).

It was just a matter for shutting down the other container and freeing the device for rtlamr. So make sure your device is not used by another process.
