Android Request has timed out n Request: method:leaveRoom params

OpenVidu v2 Issues developing apps
1

I am getting this issue in android app as well as web. Doing clean session disconnect, yet I am seeing this error especially in Android (react native). It is causing trouble as users seeing blank screens after this happens, here is the stack trace:

For some reason the message is not returning from server.

Can you share OpenVidu server logs? Do you have any way to reproduce the issue? Is it happening in production or in your development machine? What is the frequency of the problem?

Regards

Getting this error on the client end consistently right after ending the session.

Here are the logs (don’t see anything alarming):

Hello,

Even with 2.15 I am seeing this error(after a few sec. of disconnecting the session.

I am following the steps as described in the javascript tutorial. am i missing anything?

Thanks

Can you describe how have you deployed OpenVidu and the exact steps to reproduce the issue? How you leave the session, how many participants are in the session when you try to leave it?

Hello,

We deployed OV in EC2 instance and without using docker. Below are the steps to reproduce the issue:

  1. User 1 and 2 join a session using two different web applications running same version of ov browser-client (v2.15)
  2. User 1 ends the session (session.disconnect()), which broadcasts streamDestroyed event. This event is handled on both ends.
  3. User 1 side calls removeUserData immediately, when streamDestroyed is received
  4. User 2 side calls session.disconnect() and removeUserData after 3 sec. when streamDestroyed is received

Below is the error I see on the server side:

Note that same client error received in the React native client as well.

8

Is this error affecting your app in some way? Or it is just appearing in the log?

9

Short answer is yes it does.

Whereas it doesn’t impact Web based applications, yet it does effect React native based app. The exception causes the app to become unresponsive and sometimes the video screen goes blank (although this could be a separate issue).

10

Seeing Kurento error logs, can you tell what is wrong?

Definitely, would like to know what we are missing here, either in the setup or in the client code. If needed, I can privately send relevant modules from our web and react native sides.

11

disconnect() was getting called twice and was the reason for throwing above exception. Object was wrapped for safety however, wasn’t getting reset until I explicitly set it to null (after calling disconnect).

You can close this issue.
