Hello,  
I am updating the web content of my video portal from OpenVidu 2.12.0 to version 2.15.0. For this I have converted the original web content to a Docker image and have configured the file /opt/openvidu/docker-compose.override.yml to start this web content.  
Now when I intend to start a video conference through my web content, I always get an error message stating:

\<No connection to OpenVidu Server. This may be a certificate error at “http: // localhost: 5443”  
Click OK to navigate and accept it. if no certificate warning is shown, then check that your OpenVidu server is up and running at “http: // localhost: 5443”\>

Then I do not access to the media resources and never open the video meeting.

If I return the docker-compose.override.yml file to the original, then the demo call works fine.

The web environment than we want to update, on version 2.12.0 without docker is also working correctly.

Could you shed some light on the reason for this error?

Thank you very much and greetings.

Have you followed these instructions to deploy your own dockerized application along OpenVidu? [https://docs.openvidu.io/en/latest/deployment/deploying-openvidu-apps/#with-docker](https://docs.openvidu.io/en/latest/deployment/deploying-openvidu-apps/#with-docker)

Hi Pablo, thanks for your reply.  
Yes, I followed that information during startup, but it seems that the situation is more complicated, I will try to explain my environments.

Initially we set up a development environment for a video-service application on OpenVidu 2.12.0, installing on an AWS environment following the instructions of the link [https://docs.openvidu.io/en/2.12.0/deployment/](https://docs.openvidu.io/en/2.12.0/deployment/) deploying-aws /; This installation turned out without Docker, with Nginx as the web server where the values of OPENVIDU\_SERVER\_URL and OPENVIDU\_SERVER\_SECRET are configured on the document /var/www/html/js/app.js,

Now we intended to mount a more current environment for production, with the web content that we have in development, but we found that the 2.15.x installations are based on Docker. Therefore, a Docker-nginx container has been mounted where we have loaded the development web content, configuring it as follows:

The configuration of the connection variables with the Openvidu server in js / app.js is maintained.

var OPENVIDU\_SERVER\_URL = “http: // localhost: 5443”  
var OPENVIDU\_SERVER\_SECRET = “MyOpenviduPass”;

We copy the web content and the nginx configuration into the container, through a dockerfile file to create the image:  
Web content in / usr / share / nginx / html /  
Nginx configuration in /etc/nginx/conf.d/default.conf  
server {  
listen 5442;  
listen [::]: 5442;  
…

After obtaining the Docker image with the Web content, we edit docker-compose.override.yml to start this container along with the rest for the Openvidu service …

/ opt / openvidu # ./openvidu start  
Creating openvidu\_nginx\_1 … done  
Creating openvidu\_kms\_1 … done  
Creating openvidu\_openvidu-server\_1 … done  
Creating openvidu\_smartic\_1 … done  
Creating openvidu\_redis\_1 … done  
Creating openvidu\_coturn\_1 … done  
Attaching to openvidu\_openvidu-server\_1

But when trying to access the video service, you always get the indicated error message.

Can you share with us your .env configuration and your docker-compose.override.yml? It seems like your application can’t resolve localhost, Maybe you’re not running your app with `network_mode: host`.?

Hello!  
Yes, I put here a copy of this files…

I can see that the web content calls the library openvidu-browser-2.12.0.js. To update it to version 2.15.0, in this part it is enough to load and call the library openvidu-browser-2.15.0.js ?, Are there other changes to the web content part to update the version?

I can’t send you a .env file copy by here, I get the message “Sorry, new users can only put 2 links in a post”

Please, How can i send you a .env file copy?

Thanks

You can paste it here in the post. By using “`” character. In this way it is more readable. Example:

` ` ```  
DOMAIN\_OR\_PUBLIC\_IP=XXX.XXX.XXX  
OPENVIDU\_SECRET=xxxxx  
…

` ` ```

Also, It’s all services running? What is the output of `docker ps` ?

</div>

I see thah OpenVidu api is accessible via [https://css.reunionporvideo.com](https://css.reunionporvideo.com). It seems like you’re using openvidu-browser directly via browser, am I right?.

In the source code that you’re using in [https://css.reunionporvideo.com](https://css.reunionporvideo.com) at `app.js` I see a wrong variable:  
 ![imagen](https://global.discourse-cdn.com/free1/uploads/openvidu/original/1X/ad05ca9af14477b34dacf6251f864b1235ee8d95.png)

If it’s the browser the one who’s communicating with OpenVidu, this url can’t be `http://localhost:5443`. With this url, when the webpage is loaded by a client in his own browser, the browser will try to communicate to `http://localhost:5443`, so the browser is trying to communicate to OpenVidu as it is in his own machine!!

It should be:

```auto
var OPENVIDU_SERVER_URL="https://css.reunionporvideo.com"

```

I think that’s why your app is complaining about:

```auto
<No connection to OpenVidu Server. This may be a certificate error at “http: // localhost: 5443”
Click OK to navigate and accept it. if no certificate warning is shown, then check that your OpenVidu server is up and running at “http: // localhost: 5443”>

```
