c# - 来自 Docker 的多个 Mysql 连接 -> 套接字错误

Question

我目前尝试从 VM 迁移到 Docker Windows 容器。容器托管在 Windows Server 2016 数据中心上。操作系统安装在 Hetzner 托管的物理根计算机上。我的 Docker 容器包含一个控制台应用程序，用 c# 编写，对托管在 google-cloud 中的 MariaDB 数据库执行更新。

之前每个控制台应用程序都在具有自己的 ipv4 的单独 VM 中运行。现在他们在容器中运行并得到以下异常

Unhandled Exception: System.TypeInitializationException: The type initializer for 'A.C' threw an exception. ---> MySql.Data.MySqlClient.MySqlException: Authentication to host '##.##.##.##' for user '####' using

Docker 使用 NAT 网络。因此，我认为关于来自同一 IP 的多个连接的连接存在问题。

你们有没有人有类似的经验或知道如何解决这个问题？我有点困惑，很高兴能得到任何帮助。提前致谢。

如果您对我的设置或其他任何问题有任何疑问，请告诉我。

问候 迈克尔

这似乎是 MySql.Data 中的常见问题；见 bug 76597 末尾 Rui Fan 的评论寻找潜在的解决方法。
