I was trying to automate the live Streaming using Wowza Streaming Engine. For that, I installed the streaming engine in my AWS EC2 instance then I tried the following REST API for the create Application and I connected from the Wowza GoCoder using mobile.

When I do that I can’t the receive the distributed stream in JW player due to CORS error.  
So I called a REST API to update the cors. But after that my wowza Gocoder couldn’t connect the application.

Let me know what I missed on my API calls.

Please find the create API  
URL : [http://52.37.27.133:8087/v2/servers/](http://52.37.27.133:8087/v2/servers/)_defaultServer_/vhosts/_defaultVHost_/applications/may26-6  
Method : POST

Body :

```auto
{
   "restURI": "http://52.37.27.133:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/may26-6",
   "name": "may26-6",
   "appType": "Live",
   "clientStreamReadAccess": "*",
   "clientStreamWriteAccess": "*",

   "streamConfig": {
    	"restURI": "http://52.37.27.133:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/may26-6/streamconfiguration",
    	"streamType": "live-record-lowlatency",
    	"storageDirExists": "false",
    	"createStorageDir": "true",
    	"storageDir": "/usr/local/WowzaStreamingEngine/content/may26-6"
   }
}

```

Hi Ram,

The error from JWPlayer may not be related to CORS issues. It is best if we can check your Wowza instance configuration and log events. Please [create a support ticket](https://www.wowza.com/support/open-ticket) and send us the following:

- conf/

- logs/

Hi Michelle,  
I am calling update API due to the CORS issue. But after update API executes my Gocoder encoder couldn’t connect with the engine. I already opened a ticket regarding this. Still that is in open state. My ticket Id is #229918.

Hi, when you compare the XML files before and after applying the update, what differences do you see? Do you also perform a restart for the app right after sending the update command?
