Error while generate standard AX Report in Microsoft Dynamics AX 2012


I was trying to generate a standard report, naming Customer Account Statement (AR>Reports>External).

However the error message “The underlying connection was closed. A connection that was expected to be kept alive was closed by the server” prompt out after generate a report.

Besides, I also noticed that SQL Server Reporting Services stopped after I try to generate a report in Microsoft Dynamics AX 2012.

I started the services and regenerate the report in AX. Yet it still produces same results.

Is there any way to solve this issue?
