hello roberto,

thank post question on technet forum.

from error message, seems issue occurs when export report excel in reportviewer on web site. error message connection closed.

i want check whether report spends long time export excel file , generates issue. if so, consider connection closed because of service timeout. can enlarge <runtime> of reporting service. please go reportserver , reportmanager folder under c:\program files\microsoft sql server\msrs11.mssqlserver\reporting services\ , following steps.

  1. open web.config file , find line <httpruntime executiontimeout="9000" />.
  2. modify executiontimeout 9000 larger number, such 900000.
  3. save changes , restart reporting service see whether issue solved.

if have further question issue, please post freely.

regards,

edward
