The message doesn’t appear for me when I have no positioning devices connected/set up. If you don’t have a positioning device then it’s possible there’s an issue with your ArduSub parameters (maybe try resetting them?).

Interesting. That’s not the case for me, but I also run Windows as a virtual machine from my Mac, so it’s possible there are some differences in screen or something. From [a search of the QGC issues](https://github.com/mavlink/qgroundcontrol/issues?q=is%3Aissue+small+screen) I couldn’t find anything about that, so I’ve asked internally if anyone else has experienced it.

Are you able to share more information about the computer it’s running on? It may be a device-specific issue.

I’m not sure why you would want to do that, but given it’s not even managing to connect it’s presumably a network configuration issue rather than a functionality one, and I don’t expect it’s related to QGC.

Your script seems to use a custom udp port (14555) - any chance you’ve forgotten to set that up in Companion/BlueOS?
