 # Troubleshooting
 
-- I don't see the camera when using `QrcodeStream`.
-  - Check if it works on the demo page. Especially the [Decode All](https://gruhn.github.io/vue-qrcode-reader/demos/DecodeAll.html) demo, since it renders error messages. If you see errors, consult the docs to understand their meaning.
-    - Demo works but not locally: Listen for the `init` event to investigate errors.
-    - Demo doesn't work: Carefully review the Browser Support section above. Maybe your device is just not supported.
-- I'm running a dev server on localhost. How to test on my mobile device without HTTPS?
-  - If your setup is Desktop Chrome + Android Chrome, use [Remote Debugging](https://developers.google.com/web/tools/chrome-devtools/remote-debugging/) which allows your Android device to [access your local server as localhost](https://developers.google.com/web/tools/chrome-devtools/remote-debugging/local-server).
-  - Otherwise use a reverse proxy like [ngrok](https://ngrok.com/) or [serveo](https://serveo.net/) to temporarily make your local server publicly available with HTTPS.
