I followed this [tutorial](https://www.wowza.com/docs/how-to-access-documentation-for-wowza-streaming-engine-rest-api).

I am receiving this message from “swagger”. Additionally, there is no response when making calls to the REST API.

**Can’t read from server. It may not have the appropriate access-control-origin settings.**

**Server.xml**

```auto
<RESTInterface>

			<Enable>true</Enable>

			<IPAddress>*</IPAddress>

			<Port>8087</Port>

			<!-- none, basic, digest, remotehttp, digestfile -->

			<AuthenticationMethod>none</AuthenticationMethod>

			<DiagnosticURLEnable>true</DiagnosticURLEnable>

			<SSLConfig>

				<Enable>false</Enable>

**I solved the problem** My EC2 instance has an automatically generated security group for Wowza, but it doesn’t include access to port 8089 or port 8087 which is what the default Wowza REST API/API docs listen on.

I added the rules to the inbound rules myself for both ports.
