Hi Experts please help.

I have setup a ELB for 2 instances. Amazon has confirmed that my settings on ELB is fine. But when there are 2 instances my applications login page comes up but cannot login.

I checked by adding one instance after the other individually, it works normally.

What is that not allowing through ELB when 2 instances are there?
Any additional settings to be done?

    So it works well when once server is in the LB rotation? Does it work 100%  of the time directly accessing the server's individually?
