Hi. I’m trying to share my app on my local network and getting stuck. I have openvidu running locally in the docker container like so…

```
docker run -p 4443:4443 --rm --name openvidu \
-v /var/run/docker.sock:/var/run/docker.sock \
-e DOMAIN_OR_PUBLIC_IP=192.168.1.26 \
-e OPENVIDU_SECRET=123 \
openvidu/openvidu-server-kms:2.14.0

```

I created a cert and key with mkcert and I am able to access my app running at `https://192.168.1.26:8001/`.

I am able to access the openvidu dashboard running at `https://192.168.1.26:4443/dashboard/#/` and I am able to start a test session there.

I am able to make api calls from my app to the openvidu server.

But when I try to join a session from my app at I get…

`webSocketWithReconnection.js:14 WebSocket connection to 'wss://192.168.1.26:4443/openvidu' failed: Error in connection establishment: net::ERR_CERT_AUTHORITY_INVALID`

Any idea what I’m doing wrong?

Thanks.

Try opening [https://192.168.1.26:4443/openvidu](https://192.168.1.26:4443/openvidu) in the browser and accepting the certificate. Then go to your app and test it.

I am accepting the cert when going to the dashboard.

I also tried manually adding the cert to Keychain Access in Mac. After that I get a different error… `ERR_CERT_COMMON_NAME_INVALID` and `Subject Alternative Name missing`. This seems to be discussed here…

Is that something you can fix in the openvidu cert?

Are you using Docker Desktop for Mac?

If so… why are you using [https://192.168.1.26:4443/openvidu](https://192.168.1.26:4443/openvidu) instead of [https://127.0.0.1:4443/](https://127.0.0.1:4443/)?

Yes I am using Docker for Mac. I am trying to share my app on my local network.

We haven’t tested that scenario.

Maybe you can generate a valid certificate and regenerate docker image with it.

We have tested with linux and it works. But we never tested on Mac or Windows. Maybe there are some specific details to take into account.

Please share with use if you finally manage to get it working.

Did you test Chrome on Linux? Chrome seems to be the only browser having this problem. Also, does the cert used by openvidu have `Subject Alternative Name` applied? That might be the solution for Chrome according to the discussion I linked to above.

Yes, Chrome in Linux works fine when sharing openvidu-server-kms docker image over LAN, at least last time I checked. If I remember corretly, I think openvidu-server self-signed certificate was created with a very simple openssl command like this: `openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -subj '//CN=www.mydom.com\O=My Company LTD.\C=US' -keyout key.pem -out cert.pem`

Here’s some more info in case it helps track this down.

I was focussed on getting openvidu working so I could test it shared on my local network. But I didn’t realize that using a self-signed cert with https on the local network causes the websockets in my app (not related to openvidu) to fail. My websockets works over http even with the 192 ip). But when I use http and test openvidu, I am able to connect to a session, but then call to `publish` never resolves. So I have something like this…

```
console.log('*** _testVideoSession.publish');
_testVideoSession.publish(_testVideoPublisher)
.then(() => {
   console.log('*** publish ok');
})
.catch((error) => {
  console.log('*** publish error');
});

```

I get nothing after the 1st log. I don’t get `publish ok` or `publish error`. This happens even when testing on my dev machine (not just other machines on the network).

Here’s the output from the server when attempting to publish…

```

This is the same in any browser I’ve tried.

Does this help find the issue, since it’s not related to my cert or sharing on the local network. It seems to just be caused by using the 192 ip. Do the logs or the fact that the publish method never resolves help?

Thanks again.

If it is working on Firefox and not in Chrome, it is maybe related with how the browser manages self-signed certificates.

This is happening in both Chrome and Firefox. The issue that was only happening in Chrome was when I was using https.

Update… I found that the call to `initPublisher` is resulting in an error… `TypeError: navigator.mediaDevices is undefined`

Any other advice on this? To summarize… when I run my app locally with [http://192.168](http://192.168)… I get the error above when calling `initPublisher` and the the call to `session.publish` never resolves at all.

navigator.mediaDevices is undefined if you are not serving your web app on https

BRowsers eliminate Media Devices API on HTTP. So you can’t access the object: [https://docs.openvidu.io/en/2.15.0/troubleshooting/#10-my-local-video-is-not-showing-up-on-the-browser](https://docs.openvidu.io/en/2.15.0/troubleshooting/#10-my-local-video-is-not-showing-up-on-the-browser)
