Heroku- Web process failed to bind to $PORT within 90 seconds of launch. TooTallNate Websockets

Heroku wants you to use a certain port.

Add this to your Procfile to get that port:

-Dserver.port=$PORT

So yours would look like this: Procfile

web: java $JAVA_OPTS -Dserver.port=$PORT -cp target/classes/:target/dependency

Try using this:

String host = "0.0.0.0";
int port = System.getenv("PORT");

On Heroku, you must bind to 0.0.0.0 and use the port assigned to your app, which is contained in the $PORT environment variable.

From the client, you will not need to specify a port, so only wss://Heroku-Name-39329.herokuapp.com/ should be used (not the one with 5000).
