第一次来，所以要温柔
我在 C# 中和通过我的开发机器上的 snowsql 连接到雪花时遇到困难
我可以通过 .net 框架控制台项目连接到雪花。 conn.open 有效。
我无法通过 .net core 3.1 或 .net 5 控制台项目进行连接。 conn.open 挂起。
与运行的 .net 框架完全相同的代码。 在这两种情况下，我都使用 Snowflake.Data nuget。
然后我下载并尝试了snowsql并得到了错误：
<块引用>250003 (n/a)：无法获得响应。绞刑？方法：post，网址：https://...
完全相同的 snowsql 命令适用于不同的盒子。
我查看了snowsql_rt.log，我想了解一些错误。我想知道snowsql是否基于.py文件在幕后使用python。

它使用 .net 框架工作的事实让我认为它不是端口、防火墙或代理类型问题。所以我在想 python 是我的问题？
任何建议或指示将不胜感激。
