Hi I am part of a project for Otago Polytechnic's Bachelor of Information Technology course. We are trying to implement a single sign-on for some of our apps. I have managed to install Gluu on a test environment running Ubuntu 16.04.2. Installation was successful (as far as I can tell), however, when I navigate to the hostname that I installed Gluu with (gluu.staging.op-bit.nz), it comes up with a 'Server not found' message (I'm using Firefox). I have been told that the problem may be to do with Gluu running through IPv6 rather than IPv4, but I'm not sure. Any help here would be great. Note: I played around some more and changed my computer's DNS settings to those specified. Now I get a message saying that the page doesn't send any data. So it still doesn't work.
