Cannot access windows log for regular report

Hi, our environment has 2 windows server, one for AD and one of ELA server, I created a daily report on ELA server to report the failure login message of AD server, however, the report doesn't work, it only shows the header and no data in it, I tried to re-scan the windows server in the ELA console and allow this ELA server IP access to this AD server, but result is still no data in this report, anyone can give me any suggestion?
