At the most basic level, web-server/insta can't be used for a server because (a) the port is non-deterministically chosen, so it isn't reliable as a server and (b) it calls the TCP listening creation call such that it only listens to localhost. When you use serve/servlet instead, you can set the port to something particular and you can set the listening to listen to all IPs.
