If you start openvidu while there is no internet, it fails to start and an error appears.

In the system configuration, a PC is connected to the router through an internal network.  
The error is:  
dig: couldn’t get address for ‘[resolver1.opendns.com](http://resolver1.opendns.com)’: failure  
dig: couldn’t get address for ‘[ns1.google.com](http://ns1.google.com)’: failure  
dig: couldn’t get address for ‘[ns1-1.akamaitech.net](http://ns1-1.akamaitech.net)’: failure  
[/usr/local/bin/discover\_my\_public\_ip.sh] Discovery failed

What’s the problem?  
The same error occurs even if I try to set the DOMAIN\_OR\_PUBLIC\_IP item value in the .env file to 210.111.220.29 and to set the internal IP to 192.168.2.10.

What do you think is the problem? 😉 There is no internet and OpenVidu defaults are set for common cloud environments.

Try this:

1. Define in your `/opt/openvidu/.env` this environment variables:

```auto
COTURN_IP=<PRIVATE_IP_REACHABLE_BY_CLIENTS>
PROXY_PUBLIC_IP=<PRIVATE_IP_REACHABLE_BY_CLIENTS>
DOMAIN_OR_PUBLIC_IP=<PRIVATE_IP_REACHABLE_BY_CLIENTS>

```

One doubt, as of now after deploying openvidu as on-premise solution when i start the service it tries to access - COTURN IP: 14.142.3.154 which i think is public ip.  
If we dont have internet access then what ip we need to set for COTURN.  
Also do we need to install COTURN SERVER on our local machine.  
Please suggest.

What do you mean by “don’t have internet access” ?

I suppose you are talking about some kind of subnet network not reachable through public IP. Try to configure in `COTURN_IP` the private IP of OpenVidu Server in that network.

Yes, we have subnet network only.  
IP of openvidu server is - 192.168.148.186  
I have made following changes in .env file:  
COTURN\_IP=192.168.148.186  
PROXY\_PUBLIC\_IP=192.168.148.186  
DOMAIN\_OR\_PUBLIC\_IP=192.168.148.186  
But in logs it is coming as “io.openvidu.server.coturn.CoturnCredentialsService - COTURN IP: 14.142.3.154”  
How to configure COTURN\_IP and in which file changes need to be made?  
Could you please help in this?

You need to add `/opt/openvidu/.env` the parameter `COTURN_IP=192.168,148.186`. Did you deployed following official deployment instructions?

Hi,  
what means “not working”?  
Do you want to use OpenVidu only for internal communication inside your local network?

If you just want to use it inside your private network, a COTURN server should not be necessary. You would need if users behind different NATs or firewalls want to connect to each other. If I turn off our COTURN server and then start a session in our private network - all participants can hear and see each other.  
Because of this I asked you what do you mean with “not working”. Are you only missing audio and video or does the complete connection fail?

OK - your OpenVidu server is part of your private network - but the server has no public IP? It only has access to the internet over a proxy or gateway?

In this case it is normal, that external clients can not participate. An external client can’t do anything with your private it. It needs an public IP where to coturn is located or were the coturn ports (mostly 3478 TCP/UDP) are redirected to your local IP.

Change you firewall/gateway settings to foward the coturn ports to your local ip - or install an external coturn server on a host with public ip and add it to the ice-servers list in your openvidu env file. This is described here and it works for me:  
[https://docs.openvidu.io/en/2.22.0/deployment/allow-users-behind-firewalls/](https://docs.openvidu.io/en/2.22.0/deployment/allow-users-behind-firewalls/)

@poojakamra Did you restarted the server? The COTURN\_IP should be if configured in `/opt/openvidu/.env`.

Answer from @DiStefano8472 is also valid, you can setup an external coturn if you have problems.

Carlos.

After configuring COTURN\_IP i have restarted the server.  
But still it is not working.  
Also we dont have any public server for Coturn.  
So stuck with this.

When you say “not working”. What error appears in your browser side? Did you specify a reachable IP for the clients using openvidu at `COTURN_IP` ?

Hello, I have the same problem

i add `COTURN\_IP no error but when i go to [https://192.168.1.106/dashboard](https://192.168.1.106/dashboard)

i got this from browser

The error you have in your browser has nothing to do with OpenVidu itself.

Can you ping your server from the browser machine? Probably that IP is not reachable somehow, or the service is deployed but ports are not correctly opened so the browser machine can’t reach OpenVidu.

I deployed openvidu ce on promise in localhost and make FQDN

Ping is fine with [meet.test.org](http://meet.test.org) (ip : 192.168.1.106)

You should at least be connected in the same LAN as OpenVidu 😅. No internet connection does not mean that you are not connected to at least, a router or a switch which let both machines to be in the same network.
