There is a lot of reasons that can cause that error:

The first reason could be related with your firewall, it may be preventing the debugger from connecting to the server. So, please double check it.
If that doesn't work, it could be a bad initialization of the RedLink Server, please click on the following icons in the Toolbar. The first one, will provide you a status of the RedLink Server, and the second one will try to boot it; after that, please try to Debug once again.

If the issue still persists, you could delete the .metadata folder under MCUXpresso IDE workspace directory; then, debug your project.
Finally, if all the steps above don't work, you might want to reinstall the MCUXpresso IDE.

Hope any of this works out for you.

Best regards, Raul.
