I believe you have a misunderstanding of what a TURN server is for, and are calling it as if it is a standard web server.

As some of the commenters mentioned, you're not supposed to make an HTTP request to a TURN server, which uses a different TURN protocol. Instead, you configure your WebRTC setup via the iceServer object, which is where you define a TURN server. The WebRTC implementation will use the TURN servers when required.

Here's a nice article about WebRTC signaling:

And here's a couple other articles if you're interested in learning about the specific protocols WebRTC uses:
