Hello,
I have an issue with Auto-refresh. I have created a dashboard and given logic to refresh for every 2 minutes. It working fine and refreshing the report viewer but after 4 hours it was showing error as "Report Render failed". I am not getting any idea why i am getting this issue. I am working for this issue since three days but still i am unable to solve the issue. 
Can anyone please suggest be logic code for "Auto-Refresh". Thanks in advance.

Sai Krishna
