Port in use error usually means that Node-RED is already running, which is what you have found.. You just need to stop the version that is running before starting another.

Good,

Two services were apparently running here:  
node-red.service  
nodered.service

I quit the service:  
node-red.service

and disabled:  
sudo systemctl disable node-red.service

After restarting, the following error appeared:

Some settings like mqtt and telegram came with their credentials blank.

I filled it again and it worked again, I'm following up.
