Registry Manager not working


I can not browse my registry when images have been uploaded. When the registry is freshly deployed and holding no images I can click on browse and see the empty repository list. But when I upload an image and click on browse, I got always redirected to “Registry management configuration required”. Then I click on “Test configuration” which is successful and “Save configuration”. Whenever I click on browse again, I got redirected to configuration required.
Using the registry with docker command line works without any problems. I can push and pull images and when using a my web browser I can acces the registry API to e.g. list the catalog and image tags.
For further troubleshooting I have deployed quiq/docker-registry-ui. Using this web UI I can access my registry.

Any idea why the Registry Manager is not working or which logs e.g. I can check to get further information about the cause?
