SQL Server 2016 Instllation The SQL Server service account login or password is not valid

Hello,

I am trying to install SQL Server 2016 on windows server 2016 box. I have setup two domain accounts which I am using during the installation. I am planning to use one of the domain account for running SQL Server Database Engine and the other to run SQL Server Reporting Service. 

However during the installation on the Server Configuration page I am getting the following error for both the domain accounts
