Ubuntu Lanscape install problem

Hi guys. I’ve been trying to set up ubuntu landscape on my home lap. I did the quick install from https://landscape.canonical.com/set-up-on-prem.

I can nav to the IP and it takes me to the /new-standalone-user page.

I put in my new user details and click sign up, but then the next page just says ‘Hmm. We’re having trouble finding that site.’ Not sure what is going on with it. Can any one point me in a direction to start troubleshooting it?
