After I managed to get NR running at work on a Windows server, I wanted to try it at home. I had a spare laptop I loaded Ubuntu 22.04 on. I got Mosquitto and NR loaded and running in the beginning but then I had to do a hard restart when the laptop froze. Now when I go to run NR, I get the error in the title. I did some searching and looked to see what else was using that port and all I see is one NR, nothing else. I can't seem to kill it either. What else do I need to look for?

Did you setup something to automatically start node-red on boot? If so then undo that.
