Why ffmpeg stops streaming to RTMP endpoint?

I have the following Nodejs code that uses puppeteer and streams to an RTMP end point using ffmpeg :

const {launch, getStream} = require("puppeteer-stream")
const {exec} = require("child_process");
// Launch the browser
const browser = await launch({headless:true});
const page = await browser.newPage();
await page.goto("some url", {waitUntil: "load",});
const stream = await getStream(page, { audio: true, video: true});
const ffmpeg = exec('ffmpeg -re -i - -vf scale=852:480 -c:v libx264 -pix_fmt yuv420p -profile:v main -preset slow -x264opts "nal-hrd=cbr:no-scenecut" -g 60 -bufsize 3968k -c:a aac -b:a 160k -ac 2 -ar 44100 -filter:v fps=25 -f flv "' + Some RTMP URL + RTMP Key + '"');
ffmpeg.stderr.on("data", (chunk) => { if (ShowLogs == "1") {console.log(chunk.toString());}
});
// Stream to ffmpeg
stream.pipe(ffmpeg.stdin);

The code works fine, however it always stops after 17 minutes of streaming. I checked the following items :

There is no duration limitation at the RTMP endpoint. Tested with Facebook, AWS IVS...

Here are my ffmpeg logs :

Does anyone know how can I find the cause of the problem why the streaming stops ? Is there any timeout that stops the streaming ?

Thanks, Cheers,
