Yes sorry, all sorted and got it working now, I just confused myself with the “HelloVapor” project and “hello” page. Should have watched to the end of the vid first.

Can I build my Vapor 3 project on Ubuntu ECS ?

I couldn’t make it work in a browser until I tried the solution found in this thread:

```
services.register { _ in 
  EngineServerConfig.detect(hostname: "127.0.0.1", port: 8080) 
}

```

Now it works with this port. Can anyone help me figure out what’s wrong and why localhost:8080 doesn’t work?

I’m sure I don’t know what’s supposed to be in there. Here what’s in it.

```
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1 localhost

```

Anything wrong with that?

@dricard bizarre! That looks completely valid 🤔

If you run `ping localhost` in terminal does it work? If you remove the solution you added and try running your application what gets printed in the console?

Yes if I ping localhost it works. When I remove the solution and I run this is what I get in the console:

```auto
Migrating sqlite DB
Migrations complete
Server starting on http://localhost:8080

```

And when I load [http://localhost:8080/hello](http://localhost:8080/hello) I get this in Safari:

 ![03 AM](https://raywenderlich-com-v3-forums.s3.amazonaws.com/original/3X/7/2/721b0c164bc68a17a4e45e21f0adb405608250c2.png)

It does the same in Firefox:

With the solution:

```auto
Migrating sqlite DB
Migrations complete
Server starting on http://127.0.0.1:8080

```

And loading `http://127.0.0.1:8080/hello` in Safari works (I get ‘Hello World’).

Speaking to some others it may be an IPv6 issue - this should be fixed by the integration of Swift NIO soon

This is what I get from the curl:

```auto
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)
> GET /hello HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.54.0
> Accept: */*
>
* Empty reply from server
* Connection #0 to host localhost left intact
curl: (52) Empty reply from server

```

Trying with the solution returns this instead:

```auto
* Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> GET /hello HTTP/1.1

@dricard ok so it’s definitely preferring IPv6 over IPv4 - looks like there’s an issue around packets/streams for IPv6. The good news is this should be fixed pretty soon. As for why it is happening - if you add another line at the bottom of your `/etc/hosts` for `127.0.0.1	localhost` to see if it picks that over IPv6 address - or wait for the fix with your workaround til then!

@dricard either the Vapor Slack or GitHub releases. I’ll ping you when NIO hits though anyway

What is the error message you get? Knowing the error message could be useful in figuring out what is going on …

@midtownkc run `vapor update` there was a broken reflection API in Core that for some reason still is being used by the template - I’ll get that updated
