Do you have a support contract with Gluu? You are currently logged in as a community (free) user. Gluu CE is now considered legacy software and its support is limited to paying customers only. You won't be able to access repositories unless you're the one.
The current free of charge, opensource offer from Gluu is [Janssen](https://docs.jans.io/v1.0.16/). If you'll ever need help with it as a free user, you should go to its [Discussions section](https://github.com/JanssenProject/jans/discussions) at Github.
