Web Reports does not allow to Login

Hello Team

I have configured a New Bigfix Server, as part of the configuration, I have configured Web Reports for the first time. But when I try to login again with the same local web reports credentials it is not allowing me to login.
Nor, it gives any error. It just try to login and brings the login windows again with out any errors.
Kindly help fixing the issue.
Thanks
Vishnu
