Hi,

I am new to VertX. I have installed it on my computer, created a VertX project that uses the HTTPServer which has been bound to a port 8080. When i start the server using the command mvn compile vertx:run. And type http://localhost:8080 on my web browser it works.

The issue is when i place a computer or mobile device in the same network as the server and type in http://<serverIPAddressPlacedHere>:8080 no connection is made. it keeps telling me the unreachable. ERR_ADDRESS_UNREACHABLE

So how do i access my vertx HTTP server from another device in the same network?

Here is my code:

JsonObject mongoconfig = new JsonObject()
        .put("connection_string", "mongodb://localhost:27017")
        .put("db_name", "database_name")
        .put("username", mongoDBUser)
        .put("password", mongoDBpassword);
mongoClient = MongoClient.createShared(vertx, mongoconfig);


Router mRouter = Router.router(vertx);
mRouter.get().handler(this::base);
this.vertx.createHttpServer().requestHandler(mRouter::accept).listen(8080);

I am trying to understand this question, and end up with this thought:

Go to the computer which is the server and in a console type ipconfig or ifconfig and see what IP it's on, for instance 192.145.89.12 (just made that up). Now, if it's not blocked by a firewall, you should be able, on the same network, to pull up http://192.145.89.12:8080/

Or maybe I don't understand the question.

Yes it is exactly what i am trying to do. The IP is not blocked by the firewall because when i run Wamp a can access it on another computer on the same network by pulling up http://192.145.89.12/

AFAIK this will not compile; the 2nd argument should be the IP address as a String [1].

However the original code ought to bind the server to all addresses as it uses the catch-all "0.0.0.0" [2]. Could something else be blocking access to the host?

Regards,

GJ

Like listen(int, String) but the server will listen on host "0.0.0.0" and port specified here ignoring any value in the HttpServerOptions that was used when creating the server.

What port does Wamp run on? I think you've ruled out the firewall without validating that in fact you haven't firewalled port 8080.

Why not try binding your vertx server to port 80, and stopping wamp as a simple test experiment? If you can see your vertx service on port 80, then it's a firewall problem, and you should be able to google for a solution.

I have tried binding to port 80. It is still not working; cannot be accessed form another device within the same LAN.

It's probably not working on port 80 because you can't bind to a system port in user mode. You didn't see the exception because the listen method doesn't have a handler for the result.

The default host is 0.0.0.0 meaning, listening on all interfaces. So need to provide the machine IP.

I suspect your firewall simply doesn't let you reach the machine, that's all.

Can you log into the server and use curl to the specified ip address/port? 

If curl works on the server, then it's almost certainly your network configs somewhere, and not vertx.
