Error: The server is either unavailable or your connection..

ebsoft

Does anyone know about this error?

"The server is either unavailable or your connection has been lost. Do you want to attempt to reconnect?"

It seems that the client goes in timeout... in some way.. and lost connection!

Thanks

Can you describe the problem better? Are you able to connect to it? What happends after you click try again, does it connect or not?

Hi ebsoft,

I was hoping that you were able to solve the issue. I am facing the similar issue but not able to solve it.

Are you using the same build number for your RTC and NST?

A Classic report, run from either an action or a menu item in RTC, was giving me this error, too.

I'm almost embarrassed that I tried such a simple and unlikely solution, but it worked, so I thought I'd share.

In design mode for the report, I ran Tools->Create Layout Suggestion, then closed Visual Studio and the report, saving it. Then I designed it again and ran Tools->Delete Layout and saved again. The error was gone.

Obviously, you wouldn't want to do this with an RTC report, because you would wipe out the RDL.
