Sample code is not working

[icepie]

Hello i am the begginer in using openvidu.

(Full control of the UI - Basc Tutorials - openvidu-react)
sample code worked properly until last friday.

However, from the next day, the following error appeared and it did not work properly.

I am curious why this error occurs even though I did not modify the sample code.

Now it should work. Our demos infrastructure was down for maintenance.
