I have been using Mission Planner for a couple of years and have never experienced a similar problem. Suddenly the simulation cannot start, sometimes it gets to the Getting Param window but gets stuck and after a moment it displays the ‘Not Connected’ message.
I’ve tried reinstalling the program, I’ve tried minor versions, then reinstalling the latest, I’ve tried the beta version and none of them work.
I am sharing a screen recording showing the problem and also included a text file with the information shown in the command window that opens when starting the simulation.
I have had this problem for a few months now and I would like to know if there is anyone who has had this problem and how they fixed it.
