The exact error from lk-jwt-service is only `Unable to create room on SFU` with no further detail in logs. LiveKit logs nothing when this happens, suggesting the request never reaches LiveKit's RoomService. The LiveKit Go SDK converts `wss://` to `https://` for the RoomService Twirp API — it is unclear whether nginx correctly handles this Twirp HTTP/2 traffic through the `/livekit/sfu/` proxy path. + +### Problem 2: Element Web Bundles Wrong Element Call Build (critical) + +**Error:** `Unknown or unsupported from-widget action: io.element.join` + +**Root cause:** The nixpkgs build of Element Web 1.12.10 bundles the **standalone/spa** build of Element Call (`spa-3dms9gnk.js`) at `/widgets/element-call/`, but the correct build for widget embedding is `@element-hq/element-call-embedded@0.16.3`. This is a nixpkgs packaging bug. The standalone build does not use the widget API, so it makes direct Matrix API calls which fail with 401 (no access token) and does not support `io.element.join`/`io.element.close` widget actions. + +This affects both Element Web and Cinny. + +Using `call.element.io` as the frontend avoids this problem as it serves the correct embedded build, but Problem 1 (room creation) must be resolved first. + +--- + +## Next Steps + +1. Determine why lk-jwt-service room creation fails when using `wss://cyperpunk.de/livekit/sfu` — specifically whether nginx is correctly proxying Twirp HTTP/2 traffic to LiveKit's RoomService on port 7880, or whether a separate internal proxy path is needed for the API vs WebSocket traffic. + +2. Once room creation works with the public URL, use `call.element.io` as `element_call.url` since it serves the correct embedded build. + +3. Long term: track the nixpkgs fix for the embedded Element Call packaging bug, or override the Element Web derivation to inject the correct embedded build.g \ No newline at end of file
