I am trying to setup a WebRTC compatible media server, and implement (basically) a web video conference server for my company (with some other features like conference recording).
I initially tried following the directions for setting up Kurento Media Server, and the “Kurento web conference tutorial” example (Node.JS) code, but even using the code without any changes, I always got error code 40401 (Ice candidates error) from the Node.JS server application.
NOTE: I can provide the entire KMS application server log if desired.
I heard several people recommend setting up an OpenVidu server instead, so I followed the “deployment” (install) instructions (at [OpenVidu Docs](https://docs.openvidu.io/en/2.17.0/deployment/deploying-on-premises/#deployment-instructions)).
I am still getting KMS errors (from OpenVidu) related to Ice candidates…

NOTE: I can provide the complete OpenVidu log if desired.
Any ideas how I can resolve this???

You must deploy OpenVidu following the deployment instructions: [OpenVidu Docs](https://docs.openvidu.io/en/2.17.0/deployment/deploying-on-premises/)
Take a look to this page and to the Troubleshooting section at the end to check if your deployment is correct.

I did read the install instructions, and followed them (step by step).
NOTE: This was an “on premises” install. Perhaps those install instructions need to be reviewed.
The behavior that I am seeing is:
When the web browser client connects to the server, selects a “conference room” ID, and enters the “conference room” (after selecting their webcam and audio device)…
I can see the video of the local webcam,
but I can NOT see the video from ANY other client that has joined the conference
(I only see black/no video for all other clients).

1. What ports do you have opened? Rememeber to not only open them with `ufw`, open it to the outside in your cloud provider (Security groups).
2. Can you show the content of `/opt/openvidu/.env` (Without the password)?
3. Can you execute and share the output of:
```auto
sudo su
cd /opt/openvidu
./openvidu version
```

We test them, I installed OpenVIdu following installation instructions multiple times, and it is used in our Cloudformation templates
