UGS

What happened?

Hi, I have FluidNC v3.9.3 installed on my ESP32, and I’m trying to use UGS v2.1.9 to communicate with it via USB. However, every time I try, I get the following message:

‘* Connecting to jserialcomm://COM7:115200
* Connection closed’

The TCP connection works fine. What am I missing? Do I have to configure something to be able to connect like that?
