Question

I have a flex 4.5 php app that runs perfectly on localhost. When I upload it to my remote host, I come across a strange problem when I try to access the production release:

1. If I am the computer running my localhost, then the production site works.

2. If I am on any other computer then the production site returns the error: "Send failed Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'http://localhost/public/gateway.php'"

In sum, the release build is looking for files on my localhost machine. What am I doing wrong?

EDIT: (If you’re trying this example in Flash Builder 4 then it will work. The problem occurs only in Flash Builder 4.5 for PHP when you try to run the release build on a remote server (you also have to access the remote website with your localhost turned off, as the .swf grabs files from localhost)

It looks like your production SWF has some remote call that is hard coded to a localhost URL. You’ll have to find that and change it.

I’d look at all the RemoteObject, WebService, and HTTPService calls the app makes. If you use a Services-config file compiled into your app; be sure to look in there too.
