This is just a guess, but does your application require "confidential" security constraints? "Invalid Redirect" could mean that when your browser accesses port 8080, that it's being redirected to the https port (8443). If so, it could be that you don't have the hostname mapped to the IPv6 address in either your DNS or your hosts file.
The Issue is identified. Developer was redirecting the user to login page while trying to access the application for the first time. The URL returned by the application in IPv6 forms a URL like http://::1/ [Please note that square braces are not included]. The URL convention is thus not followed in the case of IPv6 where IPv4 it just work like a charm.
