当我在 localhost 上开发和运行 devserver 时，一切正常，但在服务器和域上，我无法通过 The connection was reset 消息提交此表单。下面的代码是我的 apache2 配置:

我也尝试将 uwsgi 和 mod_proxy 一起使用，但我的问题没有解决。在我通过 tshark 监控 access.log 和我的服务器端口 80 后，tshard 向我显示了这个请求，但在 access.log 文件中我不能看看有什么变化...

但现在我的问题是这个问题是如何发生的，我该如何解决？

最佳答案

我们在 Cent OS 64 位上使用 Apache 2.4 的新安装系统上遇到了同样的问题。 Apache 有时会断开连接，它落后于 nginx，所以我们经常收到 502 Gateway 错误。日志中没有任何内容，启用调试没有任何内容，没有崩溃转储等等。

解决问题的唯一解决方案 - 完全重建/重新安装 Apache。我们在将调试输出代码添加到 Apache 源代码并重新构建时找到了这个解决方案，想知道我们的调试代码如何解决问题。但它只是重新构建。

附:还要仔细遵循调试 WSGI http://modwsgi.readthedocs.io/en/develop/user-guides/debugging-techniques.html 上的建议

关于python - 格式错误的数据包 : Django admin nested form can't submit, 连接已重置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41918773/
