Failing to find ST-link

Im a having problems with finding my STLink on my Intel Nuc. When running lsusb I see the devices. But when running st-util it cant find any devices. There are other devices under this application and those have no issues.

Dockerfile:

Hi there, where is the GDB server running (i.e. st-util -p 4500) and have you ensured you can connect to it at the network level?
