http.Server.listen() was called more than once which is not allowed.

I'm having an issue:

I created an express app (hosted with A2Hosting), and attach a peer server with PeerServer({port: 7000}), but apparently it gives me an error like so:

/usr/local/lsws/fcgi-bin/lsnode.js:68
        throw new Error("http.Server.listen() was called more than once " +
        ^

Error: http.Server.listen() was called more than once which is not allowed.

Thank you, please reply to this post if you know why this error occurred

As the documentation says, you have to use ExpressPeerServer to have a PeerServer working on your already existant express app.
