How do I make the .listen work in node.js for my gcp server. I put in the external IP, and I get this error message: (repost at a more popular time)

问题

events.js:160 throw er; // Unhandled 'error' event= Error: listen EADDRNOTAVAIL 104.154.26.2:3000

104.154.26.2 is my external ip The .listen looks like this:

 serv.listen(3000,"104.154.26.2");

I know I should somehow bind the ip address to 0.0.0.0 and that there is some firewall stuff to do, but loads of time researching did nothing.
