Are web sockets in fact supported via tunnels?

Zero Trust Cloudflare Tunnel

It’s unclear from the docs as to whether WebSockets are supported via tunnels.

I"m trying to proxy a Zigbee2MQTT instance via my Cloudflare tunnel and although the web interface is running I’m getting errors on:

WebSocket connection to ‘wss://zigbee.mydomain.net/api’ failed: The operation couldn’t be completed. Socket is not connected

It seems like they “should” maybe work but I’m unsure :slight_smile:

To add more context:

I’m trying to use a Cloudflare tunnel to expose a website - and then use the cloudflare auth to access the site. It occurred to me perhaps with the WarpClient I could get this working - but I’m really looking at just exposing a website via the CF/Cloudflare Tunnel
