I’ve a module that check if stream have connections and remove if it don’t receive connection by 5 minutes. I got the stream list with:

```auto
appInstance.getStreams().getPublishStreamNames()

```

But if has some invalid RTSP, it don’t come in the list, and still appears in “Application -\> Incoming Streams” waiting for stream forever, so I’ve to enter on the engine manager and remove it manually.

How can I get this invalids RTSP and remove from Incoming Streams?

Hi,

How is the RTSP connection initiated? Is it through the MediaCaster functionality? If so, you can use the [MediaCaster API](https://www.wowza.com/docs/how-to-mediacaster-api-to-start-native-rtp-and-mpeg-ts-streams) to disconnect the stream.
