使用PDM上传Python包至PyPI时遭遇WriteTimeout超时错误的排查方案求助

我最近在尝试用PDM把自己的Python软件（版本0.8.2）上传到PyPI时，一直碰到[WriteTimeout]: The write operation timed out的错误，但另一个配置几乎相同的项目却能正常上传，而且这个项目之前也成功上传过。我昨天和今天都试过多次，结果都是同一个项目失败，另一个成功。

PDM执行的输出如下：

[nix-shell:...]$ pdm publish

The above exception was the direct cause of the following exception:

httpx.WriteTimeout: The write operation timed out

我已经排除了PyPI全局故障的可能（因为另一个项目能正常上传），现在想请教大家，我可以从哪些方面入手排查这个问题？比如：

• 是否是这个包的大小问题？（这个包是41.9MB，另一个成功的包更小一些，但之前也上传过差不多大小的版本）
• PDM或依赖库（比如httpx/httpcore）的配置有没有需要调整的地方，比如超时时间？
• 有没有可能是PyPI对特定包名或版本的限制？
• 网络层面有没有什么需要检查的点？

麻烦大家给点建议，谢谢！
