Stuck with multiplayer

Hi guys, I’m trying to implement a multiplayere setup by following the tutorial at: https://developer.playcanvas.com/en/tutorials/real-time-multiplayer/ But I’m stuck at the point where the first communication should appear. I’ve got errors like this: Failed to load resource: https://themonstr.glitch.me/socket.io/?EIO=4&transport=polling&t=NQArPHn Origin https://playcanv.as is not allowed by Access-Control-Allow-Origin. Did I misse something?
