Hello! Periodically (1 time in 2-3 days) I get an error: HTTPStreamerAdapterCupertinoStreamer.onPlaylist: Stream not found (in WowzaEngine log).

HTTPStreamerAdapterCupertinoStreamer.onPlaylist: Stream not found [stream_name/live/default.m3u8]: live
x-duration:4.908

We are use vMix with Wowza. Without Transcoder.
After a WowzaEngine reboot everything is fine. Unfortunately, the logs does not contain more detailed information than this is caused.
In vMix I see just this error message:

FFMPEG1.Exited

It would be best to open a support ticket to have one of our Support Engineers review this HLS issue:

Open a Support Ticket

They will need full vMix logs, stream name effected, and the below Wowza Streaming Engine directories for review:
[install-dir]/conf
[install-dir]/logs
