Q: I followed the Hello World! tutorial and I got it
to work in telnet but couldn't get it working in any of the browsers.
A: You missed a step
Q: I'm using App and I get 404's when I try to connect.
A: Make sure the first parameter ($host) of App is the same hostname you use to connect in your JavaScript WebSocket connection.
If you need to support multiple hosts the fourth parameter of App::route() lets you specify an alternative $host to the default in __construct.
Q: I'm using App and I get 403's when I try to connect.
A: This is actually a security feature!
App, by default, enforces a same origin policy to prevent other web sites from connecting to your server.
Either make sure you're opening WebSocket connections in JavaScript from the same URL as your $host in App
or to allow another Origin the third parameter of App::route() accepts an array of allowed origins.
Q: I can connect locally but not remotely or when I run on my server.
A: This is also another security feature!
By default Ratchet binds to 127.0.0.1 which only allows connections from itself.
The recommended approach is to put Ratchet behind a proxy and only that proxy (locally) will connect.
If you want to open Ratchet up (not behind a proxy) set the third parameter of App to '0.0.0.0'.
