BitTorrent：ダウンロードが開始しない

Question

bittorrent tracker in Laravelを実装しようとしています。しかし、ダウンロードが始まらないので、私は現時点で立ち往生していません。播種しているように見える1つのピアがあり、それが接続可能であることを100％確信しています。しかし、別のマシンで2番目のクライアントを実行すると、ダウンロードは開始されません。それは "ピアツーピアへの接続"（uTorrent）で立ち往生しています。ダウンロードクライアントで

d8:intervali1000e12:min intervali300e5:peers18:�ؤ�i�ؑ�XÚJU�6e 

を、私は、次のデータがあります：クライアントが発表行ったときに、私は次の応答を送信していますトラッカーから

私はここで何が欠けているのかよく分かりません。あなたは常に、これまで$valueを設定せずに

->header('Content-Type', $value); 

を設定しているため

多分それはですか？だから、「アナウンス - レスポンス」の形式が間違っていますか？
