python - 使用 Twisted Websocket Python 获取 SSL 错误

问题描述

嗨，我正在尝试使用 Twisted websocket 在 Ubuntu 20.0 上使用 Python 3.8.0 连接到 wss://ws.okex.com:8443/ws/v5/private。

这可以正常运行 5-20 分钟，然后我总是会遇到以下 2 个错误之一：

Traceback (most recent call last):

    raise exception_type(errors)

builtins.ValueError: unknown bio failure

但是，如果我在 Windows（相同的 python 版本）上运行它，它工作正常。我还发现这篇没有答案的帖子：How to solve OpenSSL empty Error with Twython?
