错误消息非常明确：

尝试连接到报表服务器失败。
检查连接信息，报表服务器是兼容版本。

它甚至告诉你你需要做什么！

所以请阅读消息，查看你的连接字符串，查看版本，看看是什么发生了。



很抱歉，但我们无法为您做任何事情：我们无法访问您的系统，更不用说您用来访问它们的代码了！

I am using Visual studio 2012 with framwork 4.5 for my website

and SQL server 2014 with its s-s-rS reporting feature for reports.

When I used 2012 SQL version it works fine,

but on the live server SQL 2014 is installed and I got the following error.
"The attempt to connect to the report server failed.
Check your connection information and that the report server is a compatible version."

What I have tried:

Code on my local machine is running fine where SQl is 2012 and Visual studio 2012 with 4.5 framework.

While on the server, SQL is 2014 and framework is 4.5

The error message is pretty explicit:

"The attempt to connect to the report server failed. 
Check your connection information and that the report server is a compatible version."

It even tells you what you have to do!
So read the message, look at your connection strings, look at the versions, and see what is happening.

Sorry, but we cannot do any of that for you: we don't have access to your systems, much less the code you are using to access them!
