please check if a cardano-node instance is already running:
ps aux | grep cardano-node
if yes you may kill it with:
sudo kill #pid number
I advice you to look up how to launch your node and how you should properly stop it.
If you are using some guide it should cover it.
usually these errors appear when the node didn’t started well.
type sudo systemctl status cnode or sudo systemctl status cardano-node and check the status
also you can see the logs with the command:
journalctl -e -f -u cnode.service or journalctl -e -f -u cardano-node.service
