I work for a company that is building a huge ActionScript3-based strategy game.

I am one of the developers and I am having problems connecting to the outlet.Socket works great when I use it in an internal flash drive, or perhaps when debugging from firefox. It shows output error # 2048 when I try to open the project with google chrome.

Here is the code I entered before trying to establish a socket connection.

  Security.allowDomain ("*");Security.allowInsecureDomain ("*");Security.loadPolicyFile ("mydomain.com/crossdomain.xml");

The connect function then establishes a socket connection to the server.

  instance.host = host;Instance.port = port;The socket matches the socket (host, new port); // initialize multiple sockets

Is there a server issue or even an issue caused by Chrome?If you’ve encountered the same problem and often found something helpful, take this skill test question.I am looking for a solution for severaldays, but nothing helps.

I have been doing this job in an acceptable manner for almost 2 days now, with no success. Exhausted all the suggestions I came across so I hope the community will definitely help! In my quest to answer this question very well, I hope it serves a dual purpose and provides useful information for other companies along the way. For some of them, you can see the content and TL forms; DR, but I hope you answer any questions that may involve multiple posts.

The goal is to create a “binary socket” between the Flash application and the custom socket server I’m working on. I quickly figured out that you need crossdomain.xml. A file in the current Flash application for more interoperability than just sockets.

I am doing development for Windows 7 with 64-bit version, Flash Professional CS6, Microsoft Visual Studio 2012 and hosting under IIS.

At some point I plan to host the Flash application and crossdomain.xml on a remote server, but for this development I wanted to keep everything on a separate development machine.

My Policy Socket Server module receivesIssues a request from the Flash application and returns the correct response.

Inbound Delivery with Debug -> Debug Movie -> Flash in Professional:

Accept: text / xml, app / xml, app / xhtml + xml, text / html; q = 0.9, text / regular; q = 0.8, text / css, image / png, image / jpeg, image / gif; q = 0.8, application / x-shockwave-flash, video / mp4; q = 0.9, flv-application / octet-stream; q = 0.8, video / x-flv; q = 0.7, audio / mp4, application / futuresplash, * / *; q = 0.5

User agent: Mozilla / 5.0 (Windows NT 6.1; WOW64) AppleWebKit / 537.1 (KHTML like Gecko) Chrome / 21.0.1180.89 Safari / 537.1

I was pretty sure it worked at first, until I installed a copy of Fiddler and looked at the packages that were polled and returned. I originally had a lot more entries, but when I read about crossdomain.xml in which I found almost all entries excluded in the current defaults, I deleted them to check the configuration of the unusual crossdomain.xml, I ran into this.

Only sending XML content on every socket connection did not work. I learned earlier that I need to create an effective HTTP header and then add all the XML content.

I was able to verify that the Professional Flash CS6 application has a crossdomain.xml, butwhere I enabled the application in debug mode (Debug -> Debug Movie in -> Flash Professional) and the following warning appeared in the output:

Warning: Domain 127.0.0.1 does not actually define metadirective a. Apply the “Masters Only” metadirective for offenses. This configuration is deprecated. See http://www.adobe.com/go/strict_policy_files to resolve the above issue.

I know this can be easily fixed simply by using a.xml cross-domain content like:

When I run my Flash application in full debug mode, the following content appears in the output window:

ioErrorHandler: [IOErrorEvent bubble = false type = “ioError” cancelable = false eventPhase = 2 text = “Error # 2031: Socket error. URL: http://127.0.0.1”]

Warning. The domain 127.0.0.1 has no metapolicy specified. Use only the basic default metapolicy. This configuration is deprecated. See http://www.adobe.com/go/strict_policy_files to resolve these issues.

securityErrorHandler: [SecurityErrorEvent type = “securityError” bubble = false cancelable = false eventPhase = 2 text = “Security error # 2048: Sandbox violation: file: /// C | /Source/FlashCS6/AS101.swf unable to load data from http://127.0.0.1:8080. “]

ioErrorHandler fired almost immediatelyzy after output, while securityErrorHandler can take 10 to 15 minutes. I guess this is due to the asynchronous nature of the flash engine.

While looking at the code in the debugger, I noticed that there was no polling to download the policy file until the application tried to connect to a specific URL and port. I guess this could be the reason, I’m not sure.

Added SWF and project folder to global security settings.
Changed publishing settings to “Network Access Only”
http: //127.0. 0.1 worms. finally added global security settings.
Allow Debugging is enabled in Publishing Preferences.
Windows 7 Firewall inbound and outbound rules added for TCP 8080
Multiple crossdomain.xml configuration attempts
Check all “mms.cfg” to make sure Neo contains blocking rules.
Visit functions created and included in “mm.cfg” but no log files generated anything but something already displayed in the Flash Pro CS6 output window
changed “127.0.0.1 “To allow them” localhost “, you will get the same results.You.

In a note on global security settings, I noticed that they exist in two specific locations.

If you press Ctrl-Enter and click on your Flash application, any Global Security Settings will load the last windowed dialog with options that your company can configure.
There is another one which can be found at the following URL

Should you two hire each other? I did this for both troubleshooting and troubleshooting purposes. I suspect one is coming to your local workstation while playing and the other is only on the network.

I would come across references to a sandbox type that can cause problems like this. In a small file, before connecting the sockets, I determined the current sandbox type, and it was “localTrusted” “.

Another short article was about using your ISP’s public IP address instead of localhost or 127.0.0.1, but this does not serve local development purposes.

I know that all socket communication on a neighboring machine works on 2 events. The first is LoadPolicyFile, which runs forof the entire socket request, and the second integer means that I have tested the communication of the socket server with a non-flash client application.
