Test STUN/TURN deployment:

1. First create an user to test your turn server. Execute this in your deployment:

```nohighlight
 docker exec -it openvidu_coturn_1 turnadmin -a -u testuser -p testuser -r openvidu --redis-userdb 'ip=127.0.0.1 dbname=0 password=<OPENVIDU_SECRET> connect_timeout=30'

```

Replace `<OPENVIDU_SECRET>` with your OpenVidu Secret.

1. Open Firefox and [TrickleICE WebPage](https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/).

2. Enter this:

Where `<YOUR_DOMAIN>` is the domain of your deployment.

3. If everything is ok, it should return something like this:  

4. After that, delete the test user in your deployment:

```auto
docker exec -it openvidu_coturn_1 turnadmin -d -u testuser -r openvidu --redis-userdb 'ip=127.0.0.1 dbname=0 password=<OPENVIDU_SECRET> connect_timeout=30'

```

Replace `<OPENVIDU_SECRET>` with your OpenVidu Secret.

I hope this helps,

Regards
