Plesk Already in use NODEJS - node.js

Question

I have this problem on my server using PLesk ,
Specs: Ubuntu 18.0.40.1 , Plesk
I tried to change the port to random numbers and the same results, says already in use.I would like to do the deploys well to be able to learn, I can try elsewhere but it is a priority to do it in plesk
Nodejs Config:
const app = express();
//CORS
const domainWhiteList = [process.env.ORIGIN1,process.env.ORIGIN2]
app.use(cors({
origin: function (origin, callback) {
console.log(origin)
if (!origin || domainWhiteList.includes(origin)) {
return callback(null,origin)
}
return callback('Not allowed by CORS ' + origin)
}
}));
//Uso de cookies
app.use(cookieParser());
//Activar JSON Body Leer
app.use(express.json());
//Api de Inicio de Sesion
app.use("/api/v1/auth", authRouter);
//Api Links
app.use("/api/v1/links", linkRouter)
//Port Default
const PORT = process.env.PORT || 5000;
//App se ejecuta en este port
app.listen(PORT, () => {console.log("Server is running on port:"+ PORT + " http://localhost:"+ PORT)});
