UGS as an app server? Listen for HTTPS requests?

I heard UGS can host a Docker container. What I’d like to do is, when a server session gets spun up, run ngrok.exe to receive incoming HTTPS requests, which my Dedicated Server instance will then listen for locally, and based on the requests, foreward commands to connected clients.

So, is this a complete nonsense idea? To let the multiplayer server cloud instance, listen for HTTPS requests? Would it be too deeply buried in VPS infrastructure for ngrok to punch through?

It turns out Unity has a Cloud Functions product, which I’ll try for hearing incoming requests
