 - To determine whether the problem is on Blender's side or your editor's: Close Blender and download/copy this [test script](https://gist.github.com/AlansCodeLog/ff1b246a8e31938e1c3dbfdcbb90522f) and run it with Python, and then try to connect to the server with your editor. If you're still getting problems then the problem is with VS Code, try:
       - Check your detected your Python install, or set it manually.
       - For VS Code try reinstalling the VS Code Python extension.
+- If you've been using this addon for a while and it's suddenly giving you a connection error, it might be because the default port has changed. VS Code's Python extension (vscode-python) has changed their default port from 3000 to 5678, so I have changed the default accordingly. I've made it configurable now though, so just check the port the addon is set to matches the one in your `launch.json` in VS Code.
