SRT stream not available via HTTP-FLV

[pannal]

Describe the bug
I'm pushing a h264 stream using OBS to SRS's SRT endpoint. From how I understand the documentation, this should then be exposed via /app/live/key.flv, but it's unplayable (timeout via mpegts.js and VLC). Am I missing something?

SRS is behind an NGINX reverse proxy if that helps, config:

    location / {
        include snippets/authelia/authrequest.conf;
        include snippets/proxy.conf;
        proxy_pass http://127.0.0.1:18080/$request_uri;
    }


    # For SRS homepage, console and players
    #   http://r.ossrs.net/console/
    #   http://r.ossrs.net/players/
    location ~ ^/(console|players)/ {
        include snippets/authelia/authrequest.conf;
        include snippets/proxy.conf;
        proxy_pass http://127.0.0.1:18080/$request_uri;
    }
    # For SRS streaming, for example:
    #   http://r.ossrs.net/live/livestream.flv
    #   http://r.ossrs.net/live/livestream.m3u8
    location ~ ^/.+/.*\.(flv|m3u8|ts|aac|mp3)$ {
        #include snippets/authelia/authrequest.conf;
        #include snippets/proxy.conf;
        proxy_pass http://127.0.0.1:18080$request_uri;
    }
    # For SRS backend API for console.
    # For SRS WebRTC publish/play API.
    location ~ ^/(api|rtc)/ {
        proxy_pass http://127.0.0.1:1985$request_uri;
    }

The nginx config its proxy:

location ~ ^/.+/.*\.(flv|m3u8|ts|aac|mp3)$ {
        #include snippets/authelia/authrequest.conf;
        #include snippets/proxy.conf;
        proxy_pass http://127.0.0.1:18080$request_uri;
    }

proxy to 127.0.0.0:18080, but srs config its http server listen on 8080:

http_server {
    enabled         on;
    listen          8080;
    dir             ./objs/nginx/html;
}

[pannal]

Yes, the port is remapped in docker to expose on 18080 because the port is already in use on the host machine from another service.

To be clear: this Config works when directly streaming to RTMP and using the .flv URL in VLC or mpegts.js.

Only when publishing using SRT the flv is not available/doesn't load (times out).

[pannal]

Can I get you some logs? Any debug settings I need?

Edit: Updated the first post with the docker config and specific version of SRS 6.

Is the http://127.0.0.1:18080/live/livestream.flv plays well in your localhost?

[pannal]

It plays well using RTMP and playing via the external https://domain/live/livestream.flv, yes (via the NGINX location, which uses http://127.0.0.1:18080/live/livestream.flv).

But not for SRT.

[suzp1984]

I tried your srs conf, SRT publish and http-flv plays well in my machine.

ffmpeg -re -i source.flv -c copy -f mpegts 'srt://localhost:10080?streamid=#!::r=live/livestream,m=publish'
ffplay http://localhost:8080/live/livestream.flv

Try above two cmds, check in your env.

[pannal]

Does ffplay http://localhost:18080/live/livestream.flv work as well? Because that's the port used for exposing the streams.
