Nginx Tornado WSS and PHP

Question

Good morning,

I have the following concern, I am trying to configure NGINX with SSL with 2 applications (subdomains), one is with WebSocket (Python-Tornado) and the other is a manager developed in PHP.

The server scheme corresponds to my https://ws.example.cl (Tornado-wss) with proxy or internal redirection to 127.0.0.1:8888 and the php application in the domain https://app.example.cl directly entering port 443.

My big question lies in feasibility, is it possible to make it work? or how should the proxy structure be configured with WSS in NGINX?

Greetings.
