myasp.net託管數據庫服務器未找到錯誤

Question

我已將我在vs2010中構建的asp.net網站移動到虛擬主機myasp.net。我試圖連接到數據庫，但它們的默認連接字符串爲：

Data Source=SQL5024.myASP.NET;Initial Catalog=MYDBNAME;User Id=MYUSERNAME;Password=YOUR_DB_PASSWORD 

不起作用。它拋出這個錯誤：

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

錯誤消息的其餘部分如下：

[SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

我曾嘗試編輯連接字符串包括服務器和端口，如下所示，但它似乎沒有不做出改變。

Server=SQL5024.myASP.NET,1433; 

我相信網站上的SQL Server版本是2014年。我已經重新我用本地信的數據庫，所以我不明白是什麼問題。我錯過了與實例有關的事情嗎？

Answer 1

事實證明，我需要編輯web.config中的連接字符串以及該頁面的後端代碼。業餘的錯誤，但也許這可以幫助有類似問題的人。
