Hello, I am a beginner. I can run the webrtc example normally, but there is a serious echo. How do I set it up to cancel the echo? I referenced ：

Are you running publish and play on the same computer and browser? Are you trying to run the meeting example on GitHub?

I successfully generated the link to the participant. My link was written incorrectly and should be changed to:

[https://localhost.streamlock.net/meeting/createMeeting.html](https://localhost.streamlock.net/meeting/createMeeting.html)

Now it works properly, thank you very much!

Thank you for you replay! When I run the meeting example on GitHub I have a problem.I followed the steps on Github to modify the file, but when I open the createMeeting.html file and click the Create Meeting Links button, the link becomes like this: “[http://127.0.0.1/webrtcmeetingfiles/meeting/\<%](http://127.0.0.1/webrtcmeetingfiles/meeting/%3C%25) **LOCATION** %%3E?action =createChat”

And the error in console is like this:
