Can stream via SRT to MonaServer/MonaTiny but cannot access that stream

[maltris]

Hello,

I am trying to utilize MonaServer/MonaTiny to stream to a server and then fetch that stream from there. With RTMP this works perfectly fine, however I wanted to check out SRT:

ffmpeg -re -i ~/myvid.webm -f mpegts 'srt://127.0.0.1:9710/?streamid=1'

ffplay "srt://127.0.0.1:9710/?streamid=1"

The sender transmits, but the receiver will not be able to fetch any stream. Just empty.

The debug log looks like this:

My setup is running in docker but for debug purposes in host networking mode:

docker run --rm -it -v "./MonaServer.ini:/usr/local/bin/MonaTiny.ini" --net=host --name=mona monaimage

The libsrt is 1.5.3 (from Alpine 3.19), MonaServer is commit 13b4eb45705b7ebff2dd6cd93ad11d43aea45dc1.
