Cannot connect to GRBL controller

My controller has been connecting just fine. When I tried to connect this morning I received the following message in Lightburn when I try to connect.

That looks like the controller is using a different Baud Rate setting than LightBurn is, or the cable / connection is bad.

I checked the baud rate they were the same and replaced the cable and it solved the problem.
