I’m having the issue too at [bittorrent/stages/qv6](https://app.codecrafters.io/courses/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)](https://github.com/shide1989/shide1989-codecrafters-bittorrent-rust/tree/master)

@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

@shide1989 I tried running your code, but it hangs both with `codecrafters test` and when run locally.

Could you try running this command locally to see if it hangs or works for you as well?

```auto
./your_bittorrent.sh magnet_download_piece -o /tmp/torrents1485664656/piece-1 "magnet:?xt=urn:btih:ad42ce8109f54c99613ce38f9b4d87e70f24a165&dn=magnet1.gif&tr=http%3A%2F%2Fbittorrent-test-tracker.codecrafters.io%2Fannounce" 1

```

Somewhere in the process I was missing a “send interest” message, due to the new code for the magnet link.

After adding it, it worked just fine.

Thanks for your help !

(now I just have to get a free Membership week to be able to submit it lol)
