Hey @conchimtucgian, welcome to the Community!
I’m sorry for the trouble. Could you please check the following?
- Does your connection allow WebSocket connections,
ws://orwss://, in addition tohttpandhttps? We use WebSocket extensively for those screens.- You can check whether WebSocket is working here: Real-Time Web Test - Does your browser support WebSockets?
- Are you behind some kind of firewall or proxy?
- Could you please try again?
Please let us know how it goes.
