Wowza player: Error 2048

Hi guys,

I’ve set up an environment using Wowza Streaming Engine, Streaming Cloud and Wowza player.

I send an IP camera live stream to streaming cloud (CDN), and my public website shows the video through wowza player.

The vast majority of users can see the live feed without problem, but some people sees a “Stream unavailable” error. I looked at firefox and IE error console, and I can see this line:

00:00:08.969 WARN: TransportHTTPURLLoaderConnection: onSecurityErrorHandler: [SecurityErrorEvent type=“securityError” bubbles=false cancelable=false eventPhase=2 text=“Error #2048”]

00:00:08.976 WARN: AssetPlayerBase: Error occurred: Playlist failed to download.

I tried activating CORS on my Stream target, but that doesn’t help.

Thank you


I added the property and value to the live application:


Access-Control-Allow-Origin: *

and it worked partially.

The problem is when someone uses IE 10 or older. The wowza player switches to FLASH, and even if I configure the crossdomain.xml, I get a Stream Unavailable error.

Is there something I can do to fix that?

Hello @Maxime Phaneuf,

I see that you opened a ticket with our support team regarding this issue and their suggestion was to install the latest update for Wowza Engine.

Did updating the Wowza Engine software resolve this issue for you?
