Cannot connect from SmartDashboard()

[Thundrio]

I have been unable to get my SmartDashboard to work no matter what I try. I have downloaded it and I believe it is configured correctly (it auto launches with the DS and our team number is set in preferences) but the connection widget is stubbornly staying red, not green. The Driver Station says we are connected and I can drive the robot, but the widget is staying red. Do I add anything in my code to set it up, and if not what could be wrong?

I don't care about anything right now except turning that stubborn widget green.

Thank you in advance.
