Portal server not listed under "browse servers"

If I create a portal experience it is only listed in the browser when I do a search for it by name. Other servers in my region and in other regions, when you click,' portal, browse" there are a whole bunch of available servers listed even with a ping of 500. So, my question is what I am doing wrong when creating or hosting an experience? How do I get the server to be listed under the server browser? I have attached two photos of the server browser.
