Rest API Swagger doesn't return detail

I followed this tutorial

But swagger returns nothing when expand operations/ show hide.

and here’s my server.xml

Hi @Marra Lin, sorry for the delay. Looking it over, tech support has let me know they will need a support ticket to check the overall config, including the ports and potential firewalls.

You can submit one here:
