Report Server Error after 1.5 hours

We have a large report that we are running on the report server. After 1.5 hours it presents the following error. Is there somewhere we can look at a log to find what causes it?


There is a property for a timeout in the advanced settings (Timeout for report generation)
What is your current setting?


Yup, that is it, it is set to 90min. Thank you

It’s great you got your answer very quickly.
