This one is a niggle rather than an issue. My camera connects and I get either images remotely or streaming video across the network just fine, but this message pops up at the bottom of the screen, often in multiple windows

SocketException : Failed host lookup: 'camera-signaling.prusa3d.com' (OS Error: No address associated with hostname, errno = 7)

Oddly, the error doesn't indicate any glitch in the video or degradation in performance at all. Rebooting the camera doesn't appear to help either.

Anyone else seen & solved these? 

This is the Buddy3D for the Core One. It reports 74% signal quality, Firmware v3.1.0 & H/ware NB.1.1.0

Thanks
