Csv reports timing out despite size of the report being too small

Hello @Ananth_Balasubramani

Welcome to the community!!

The Kibana version 6.8.23 is an older version. Also was the reporting working in your environment & stopped suddenly or it works intermittently or it never worked in past?

Still looking at the issue you are facing could you please review below threads if it can be of any use :

Thanks!!
