Improve error messaging when extension can't talk to launched debugger #140

Open arosien opened 3 years ago

arosien commented 3 years ago

If the backend debugger fails to launch, currently the extension shows an (unfriendly) error message

connect ECONNREFUSED 127.0.0.1:4711

It would be a better experience to instead say the extension couldn't connect to the backend and provide some suggestions as to how to fix or debug the problem.
