Getting timeout #qv6

I’m having the issue too at bittorrent/stages/qv6

My code works just fine when using cargo run download sample.torrent -o /tmp/test.txt.
But using the same parts of code to download pieces from a magnet link, I get the timeout issue when running the codecrafters test (or submit) commands.

My Rust code is available at GitHub - shide1989/shide1989-codecrafters-bittorrent-rust: Build your own BitTorrent challenge ! (in Rust)

@shide1989 I moved your post to a standalone topic, since it seems to be a separate issue.

I’ll look at your code shortly. In the meantime, could you try adding logs for the download progress to see how far it gets before timing out?

I also tried to limit the simultaneous tcpStream writes sent to 5, to see if I was getting some kind of blocked, but it didn’t change anything
