Problems in v2.20.2 in my server when I run /openvidu-health-checker

OpenVidu v2 Issues with deployment

Michel_Rodriguez December 22, 2021, 6:54pm 1

Hello
When I run the sudo docker this command:

run --rm --shm-size 2g -e OV_URL=XXXXXXX -e OV_SECRET=XXXXXXXXXXXXXXXXX openvidu/openvidu-health-checker

That is the output:

I am seeing lots of SSLCertVerificationErrors. Make sure your endpoint has a valid domain and SSL certificate.

cruizba December 23, 2021, 2:47pm 3

Aah, yes, the healthchecker does not allow selfsigned certificates. I think I will add it. You need to use a valid certificate.

Michel_Rodriguez December 23, 2021, 5:18pm 4

Now I made changes and I am using the Let’s Encrypt certificate. After these changes it no longer showed the certificate errors when running the healthchecker, now it shows me this other error:

Is the problem related to port problems?

I had an application that used openvidu-browser and API 2.16.0 and 2.16.0 on the server, after updating to version 2.20.0 on the server the application continues to work with version 2.16 and 2.17 of openvidu-browser, but with version 2.20 of the js it doesn’t work for me. With js version 2.20 the editor works fine, but the subscriber cannot connect to the video, it keeps loading indefinitely, in the browser console it shows me the following warning:

OpenViduLogger.ts:255 StreamManager of Stream XXXXXXX (Subscriber) did not trigger “streamPlaying” event in 4000 ms

cruizba December 24, 2021, 12:34pm 5

This openvidu health check should be executed outside the deployment. From what I can see in your logs you’re executing that in the same machine. But anyways I think this error is due to your Coturn not running correctly and not configured correctly in OpenVidu.

What ports do you have opened? Do you have port 3478 and 40000-65535 publicly accesible?
Can you show me the output of:

docker logs openvidu_openvidu-server_1 | grep 'COTURN IP'

Is the IP of the previous command your public IP?

cruizba December 24, 2021, 12:59pm 7

Context: I think the Public IP is not being discovered correctly, and a wrong Public IP is reaching the browser.

Do you have external DNS requests enabled? What this command output to you?:

dig @ns1.google.com o-o.myaddr.l.google.com TXT -4 +short | tr -d \"

If this command timeouts with an error, this would be the cause of your OpenVidu instance not autodiscovering its public IP.

In that case you can:

Enable outgoing requests through port 52 to external DNS services.
…or…
Add the public IP by hand:
1 ) Replace /opt/openvidu/docker-compose.yml from this in the coturn section:
```
--external-ip=$$(detect-external-ip)
```
to this:
```
 --external-ip=<YOUR_PUBLIC_IP>
```

2 ) Add this environment variable in /opt/openvidu/.env

COTURN_IP=<YOUR_PUBLIC_IP>

Michel_Rodriguez December 24, 2021, 4:00pm 8

Hello thanks for your answers

When I run this command: docker logs openvidu_openvidu-server_1 | grep ‘COTURN IP’
This returns the correct public IP of my server.
When I run this other command: dig @ns1.google.com o-o.myaddr.l.google.com TXT -4 +short | tr -d "
This returns the correct public IP of my server too.

The problem is the following after updating the server to version 2.20, my application works fine using openvidu-browser 2.17, but when I change this js to version 2.20, the video editor works correctly, but the viewer never watches the video in the editor and in the viewer’s browser console it always shows these warnings:

OpenViduLogger.ts:255 StreamManager of Stream str_CAM_HmKi_con_Zqzezrjzp0 (Subscriber) did not trigger “streamPlaying” event in 4000 ms
OpenViduLogger.warn @ OpenViduLogger.ts:255
(anonymous) @ StreamManager.ts:582
chatroom.php?db_id=3980701:617 ExceptionEvent {hasBeenPrevented: false, cancelable: false, target: Session, type: ‘exception’, name: ‘NO_STREAM_PLAYING_EVENT’, …}

The functionality of my site is as follows an editor that many viewers can connect to. Only one video is streamed per session. Viewers never play their own videos, they can only watch the publisher’s video.

Thanks and have a good Christmas.

Hello @Michel_Rodriguez , have a good Christmas too

What I would recommend in such cases where you need to update from version to version is, instead of going from 2.17.0 to 2.20.0 directly, go first to version 2.18.0, then 2.19.0, and so on…
In this way you can check in release notes for each version what breaking changes could be between versions and do all necessary changes if you are affected by those breaking changes.

The other possiblity is to guess what is happening in your update from 2.17.0 to 2.20.0, but it will be harder:

To check if it is a deployment issue, you can test your app pointing to our demos deployment, which serves version 2.20.0 right now:

OPENVIDU_URL: https://demos.openvidu.io
OPENVIDU_SECRET: MY_SECRET
Are you using OpenVidu directly from the browsers? Or do you have a backend logic?
If you are using a Backend, make sure that the client is updated also, or if you are using Rest API requests, check that there are no breaking changes affecting you. Check release notes
Do you have warnings logs regarding deprecated calls in your OpenVidu server?
