Describe the bug (actual behavior)

Hi Team,
I am encountering the same error on my side.

I have created a docker-compose.yml file with two images: frontend and backend.

Frontend: Using Nginx to re-route traffic with SSL.

Backend: Kafka application enabled with OAuth configuration, using a .jks certificate along with key and URLs.

SSL is enabled, and I am able to see the cluster, configure a new cluster option, and view the option to create new topics.

Issue: When I try to add a new cluster or create a new topic, I receive a 403 error.

Did I miss any configuration, or is there something additional that needs to be added?

Please suggest.

Config File:

docker-compose.yml

roles.yml

nginx-conf.yml

Expected behavior

No response

Please try to add role.yaml into your SPRING_CONFIG_ADDITIONAL_LOCATION path
Like /etc/kafkaui/roles.yml

Here am facing different issues.

Once I added the roles.yml as you recommended, the UI no longer shows cluster details (it appears empty). Still, I’m unable to create topics or other configurations — the same error occurs as before.

"https://kafkaui-domain.in/ui/clusters/CLUSTER/all-topics/create-new-topic"
However, if I provide the complete URL, I can see the broker details
