Unknown action: connect

Wowza Streaming Engine
1

Hi, I send request:

http://XX.XX.XX.XX:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/streamfiles/tst1.stream/actions/connect?connectAppName=Live1&appInstance=_definst_&mediaCasterType=rtp

tst1.stream - is present

Live1 - is name of my application

defaultServer and defaultVHost - OK

Manually this application connect to this stream successfully

But remotely my program receive:

<wmsResponse>
<success>false</success>
<message>Unknown action: connect</message>
</wmsResponse>

What is my mistake? Thanks.

Hello there, try this same call but remove the .stream from the file name.

send request without extension “.stream”

http://XX.XX.XX.XX:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/streamfiles/tst1/actions/connect?connectAppName=Live1&appInstance=_definst_&mediaCasterType=rtp

and receive answer

Hello,

First I want to make sure you are following the example form this article:

https://www.wowza.com/docs/stream-management-query-examples

I do see that you have posted what appears to be the end section of this call:

curl -X PUT --header 'Accept:application/json; charset=utf-8' --header 'Content-type:application/json; charset=utf-8' "http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/streamfiles/metallica/actions/connect?connectAppName=testlive&appInstance=_definst_&mediaCasterType=rtp"

Can you confirm that the opening section of this call matches the call you are making?

Have you been able to make other successful REST API requests to this server?

Regards,

Jason Hatchett

Hi @Anders Hammer and all the community. When upgrading to 4.8.0 in Windows systems, you may need to install some additional C++ libraries in order for SRT ingestion to keep working as expected. This is further described in the notes here: https://www.wowza.com/docs/ingest-and-publish-an-srt-stream-with-wowza-streaming-engine

If the above doesn’t solve it, we recommend opening a support ticket providing your server /conf and /logs folders for further inspection

Hi @Alberto Cabaleiro,

Thank you, installing the latest C++ redistributable solved the issue on all servers!

I have just updated our Wowza farm from 4.7.7 to 4.8.0 and now I’m getting this error on 4 out of 10 servers (all Windows). None of the servers reported error during upgrade. I have tried restarting one of the servers but it still returns this error.

I’ll demonstrate all the REST API calls below.

Get stream files:

http://hostname:8087
/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/streamfiles

Returns:

{
    "serverName": "_defaultServer_",
    "streamFiles": [
        {
            "id": "myStream",
            "href": "/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/streamfiles/myStream"
        }
    ]
}

Get stream file:

[http://hostname:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/streamfiles/myStream](http://hostname:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/streamfiles/myStream)

Returns:

{
    "version": "1591450261539",
    "serverName": "_defaultServer_",
    "name": "myStream",
    "uri": "srt://0.0.0.0:10000"
}

Connect stream file:

http://hostname:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/streamfiles/myStream/actions/connect?connectAppName=live&appInstance=_definst_&mediaCasterType=srt

Returns:

<strong>{
    "success": false,
    "message": "Unknown action: connect",
    "data": null
}</strong>

Trying to connect it in the GUI results in the same message:

The error log confirms it:

ERROR    server    comment    2020-06-06    21:47:50    -    -    -    -    -    74865.239    -    -    -    -    -    -    -    -    REST API: Unknown action: connect

In the access log there is a Java error right before the “Unknown action: connect” message:
