Publish controll handler is not getting called

Hey,
i implemented a publish control handler on our product to manage publishing a webcast.
My setup:
I am running a nimble server inside a docker container and connected the server to the wmsPanel.
I configured rtmp ingest with an interface and an application.
Ingest is working for the route: rmpt://localhost:1935/live/test/<anyKey>
I am able to watch the hls stream at the route:
http://localhost:8081/live/test/<anyKey>/playlist.m3u8
I configured a publish control handler route:
http://host.docker.internal:8080/api/webcast/publish_control
host.docker.internal is necessary on mac OS. Its basically calling localhost. I tried to call the handler with the exact same url and the handler was responding correctly.
Now i tried to ingest via RTMP again and i noticed the handler is never called. I configured rtmp auth for the application.
Is this a problem when using rtmp auth and the publish control handler? When i look at the schema graph on the corresponding blog posts it looks like it should work. Does anyone have experience with publish control handler configuration?
Am i missing an obvious thing?
Hope you can help me.
Greeting!
Dennis

Hello, Dennis.

Please note, we didn't check Publish Control with macOS Docker, as we didn't intend it for such usage.

Setting an RTMP password will enable a Publish Control signature and block users that are not allowed.
I suggest launching a ticket at wmspanel.com/help to continue the discussion.
Please also share your handler code.

Thank you.
