将音频文件加载到模板会导致ConnectionResetError:[Errno 54]由对等方重置连接（Django，Python）

我正在使用Django制作一个音频播放器webapp。音频文件由管理员通过一个模型上传，该模型将文件添加到我的媒体目录中。然后，在我的模板中，音频文件与单个音频播放器一起显示

{% for song in songs %}
   <audio class="player" controls>
      <source src="{{ song.audio_file.url }}" type="audio/wav">
   </audio>
{% endfor %}

这可能是什么原因？非常感谢您的帮助
