Displaying local server in Screenly

Did you try the experimental version of screenly to see if the Qt Browser can handle this?

if not, i can help you run a google chromium instance to show this but that is not a screenly-ose type of configuration, it is something i can advice you on how to do but should not be taken as something that deals with screenly-ose, it’s like a personal method I can show you just to help you out.
