Webrtc/udp server possible (the render.com server will be the central peer)?

I have my clients connect to the server using webrtc. Heroku seemed to disallow this and I am getting the same error on render. Is it not allowed on render too? Is there any way to bypass it?

I am using a node.js for the server and simple-peer.js for webrtc.

We only permit http to services, if it’s possible to use webrtc over HTTP then it should work - but if it’s not then I’m afraid not.
