@jakaskerl code is really simple:
with dai.Device(pipeline, device_info) as device:
print(f"Device: '{device.getDeviceName()}' {device.getDeviceInfo()} Sensor: {device.getCameraSensorNames()}")
camera is on a remote network, where I have other cameras. The not working one goes through different switches and routers. Port 80 works, as I see the UI (script has an http server) The problem is, I can't connect to it with the load a new program, so most probably there is an issue with ports 11490/tcp and 11491/udp. Looking at the network setup through the route all seems fine, but it isn't. So to debug the issue I was asking for more information, as you can see from the error message the system does find the device, it's IP and its MXID, but says X_LINK_DEVICE_NOT_FOUND
Maybe you can point me to the right directions, I've no idea about the inner workings of the depthai library
