Server Trial Expired? Only one Device.

I might be confused about how the licencing worked but I thought it was free for 1 device. Currently, I am forwarding 1 port from my raspberry pi 4 to my windows 10 machine and the virtual client on my windows 10 machine sees the port and when I right-click to use the device is getting an error stating the trial has expired.

The device in question is a 3D printer that is hooked up to the Pi.

Any help appreciated. Thanks.

It will say that if you are using the server in a way that requries a license.
