We have a issue when generate a report in the report viewer with a timout, see below. I have tried to set multiple timout settings in IIS and Web.config but nothing helps. The strange thing is the query in the SQL database doesn't take more then a minute, so it seems like a connection issue between the application server and the database server. It is quite a lot of data, so maybe that is the issue?
