本地调试是好的，发布到服务器上就报错了。是什么原因？

同样的数据库链接，本地调试查询正常，发布到服务器查询返回500.
发布到服务器后，就不能打印日志输出了。
所以，把查询语句用异常捕获包一下，如下图，返回异常信息到前端显示。

查询异常信息如下：
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 35 - An internal exception was caught)
