Accessing Docker assets json results in 500 on https

Nexus 3 M5 running on local IP number via https and http.

Browsing to an asset of a docker repository works fine and I can go to a specific asset and click on the link for the json doc and get it rendered in my browser with an example URL like http://localhost:8081/repository/docker-all/v1/images/a04ebe635e69a3a3805f1d8e78f89559eef6db0bcea13868381015e7c2b92c66/json

Works with the localhost IP number as well.

However when I do the same under the https url it does not work and I get an error 500 page in Nexus with the short message javax.servlet.ServletException: Filtered request failed.

I also tried setting base url capability in various combinations but could not get it to work. There is no stacktrace in the console log.
